Operator brief

  1. Rising

    U.S. DoC signed nine letters of intent allocating $2.013 billion under CHIPS Act for quantum hardware and foundry developers; GlobalFoundries simultaneously launched a dedicated Quantum Technology Solutions business unit with active customer engagements. Federal quantum manufacturing support is moving from policy to procurement.

  2. Rising

    NVIDIA's GTC Paris announcements cover a Germany-based 10,000-GPU industrial AI cloud (DGX B200 and RTX PRO), Blackwell infrastructure partnerships across European nations and enterprises, DGX Cloud Lepton compute marketplace expansion, and separate AI factory commitments for Saudi Arabia and Taiwan. Sovereign AI infrastructure spend is transitioning from pilot to named deployment at scale.

  3. Blocker

    EIA's Annual Energy Outlook 2026 projects U.S. data center server electricity reaching 446-818 BkWh by 2050. Coal retirements in 2025 came in at 2.6 GW, the lowest annual figure since 2010, with 4.8 GW of planned retirements deferred and 1.1 GW cancelled. Virginia commercial electricity grew 30 million MWh in six years. Grid capacity is now a structural constraint for AI infrastructure expansion timelines.

Quantum

  • P1 U.S. DoC $2.013 Billion CHIPS Act Quantum LOIs

    Nine non-binding letters of intent bring federal quantum hardware investment into execution range across hardware and foundry developers.

    The read: LOIs are pre-contractual, but the simultaneous scope across nine developers signals a concerted effort to build domestic quantum fabrication capacity rather than rely on offshore foundries. Execution depends on contract conversion, which has historically taken 12-24 months from LOI stage.

  • P1 GlobalFoundries Quantum Technology Solutions Launch

    An established high-volume contract semiconductor manufacturer formally enters the quantum hardware fabrication market.

    The read: Dedicated foundry capacity from a volume manufacturer removes a key commercialization constraint for hardware developers previously dependent on academic or boutique fabs. The DoC announcement accompanying the launch suggests alignment with the CHIPS Act LOI portfolio.

  • P2 Flatiron Institute/CCQ: Classical Simulation Challenges Prior Supremacy Benchmark

    Researchers at the Simons Foundation's Center for Computational Quantum Physics published work showing classical simulation methods can replicate outputs previously attributed to quantum advantage.

    The read: This result narrows the specific benchmark rather than the field. Quantum hardware continues to progress on error correction and qubit counts. But it reinforces the principle that supremacy claims require sustained peer scrutiny before operators treat them as architectural decision inputs.

  • P2 Quantinuum and bp: Seismic Imaging Collaboration Scales from Pilot

    A quantum-hybrid seismic imaging project transitions from a completed feasibility pilot to a production-oriented scaling phase targeting complex geophysical wave physics.

    The read: Industrial quantum applications reaching production-scale trials remain uncommon. Seismic imaging is compute-intensive, and hybrid speedups in wave physics modeling could carry direct economic value for energy exploration before fault-tolerant quantum systems are available.

  • P2 Xanadu: QROM Toffoli Overhead Reduced ~50%; Nasdaq/TSX Listing

    Xanadu published a QROM optimization reducing non-Clifford Toffoli gate overhead by approximately half, and completed a public listing on Nasdaq and TSX (ticker: XNDU).

    The read: The algorithmic result is peer-verifiable and meaningful for any algorithm with QROM-heavy memory access. The public listing creates a capital-markets reference for quantum hardware company valuation that was not previously available.

Chips

  • P1 AMD EPYC Venice: TSMC 2nm Production Ramp

    AMD's next-generation server CPU enters volume production on TSMC's 2nm process node.

    The read: A high-volume datacenter CPU entering production on 2nm is the clearest validation yet that the node has moved from risk silicon to commercial yield. This is a supply-side timing signal for system integrators planning next-generation datacenter builds on 2nm-class silicon.

  • P2 Chiplet Economics: Cost Rises Are Not Automatic Disqualifiers But Require Accounting

    A Semiconductor Engineering analysis examines conditions under which chiplet disaggregation raises total system cost and what forces might change that trajectory.

    The read: The cost trajectory for chiplets is not automatically favorable over monolithic dies, particularly at low volumes or for designs where yield improvement does not offset packaging overhead. As AI accelerator packages grow more complex, per-unit packaging cost is a design variable.

  • P2 Low-Temperature Solders: Material Reliability Constraint for Chiplets and Photonics

    Warpage, thermal sensitivity, and brittleness in low-temperature solders are creating reliability risk in complex multi-chiplet and photonic packages.

    The read: Photonic co-packaging, targeted for next-generation AI interconnects, is entering the same thermal budget and material reliability space as advanced chiplet packaging. This is an active manufacturing constraint, not a future concern.

Power

  • P1 EIA AEO2026: Data Center Server Electricity Projected at 446-818 BkWh by 2050

    The U.S. government's primary long-range energy forecast shows standalone data center server consumption growing faster than all other data center room types, with the 2050 range spanning nearly 2x depending on scenario.

    The read: A 2x spread between scenarios is operationally significant. Operators building 10-plus-year infrastructure plans should stress-test against the high scenario; the gap implies that efficiency improvements alone cannot be counted on to flatten demand.

  • P2 ERCOT: Utility-Scale Solar Forecast to Exceed Coal Generation in 2026

    EIA projects 78 BkWh of utility-scale solar generation in ERCOT for 2026, projected to exceed coal output in that grid for the first time.

    The read: Texas is simultaneously the largest data center growth market in the U.S. and the region where this generation-mix crossover is occurring. For AI infrastructure operators, this shifts the renewable energy credit landscape and the average carbon intensity of Texas grid power.

  • P2 Coal Retirement Slowdown: 2.6 GW Retired in 2025, Lowest Since 2010

    Planned coal plant retirements are being deferred or cancelled, keeping older generation capacity online longer than projected.

    The read: Deferred retirements reflect grid reliability pressure from accelerating load growth. For AI infrastructure operators, the practical consequence is a dirtier average grid mix in major data center regions for longer than earlier retirement schedules implied.

  • P2 Virginia Commercial Electricity: +30 Million MWh (2019-2025)

    Virginia's commercial electricity sales grew 30 million MWh in six years, the fastest growth of any state except Texas, driven primarily by data center concentration.

    The read: Northern Virginia's utility infrastructure is now co-located with a material fraction of U.S. AI infrastructure. Utility interconnection capacity in that corridor is a direct constraint on new data center deployment timelines, not merely a cost variable.

AI Compute

  • P1 NVIDIA European AI Infrastructure: Industrial AI Cloud and Blackwell Partnerships

    NVIDIA announced a Germany-based industrial AI cloud with 10,000 GPUs (including DGX B200 and RTX PRO Servers), alongside Blackwell infrastructure partnerships across European nations.

    The read: These announcements are deployment commitments, not roadmap items. The industrial AI cloud framing signals NVIDIA's intent to position as infrastructure provider to manufacturers, not only to hyperscalers. The convergence of sovereign AI policy and industrial use case is shaping the next tranche of GPU demand.

  • P2 NVIDIA and HUMAIN: Saudi Arabia AI Factory Partnership

    NVIDIA and Saudi Arabia's HUMAIN, a Public Investment Fund AI subsidiary, announced a partnership to build AI factories in Saudi Arabia.

    The read: Sovereign AI infrastructure commitments across Europe, the Middle East, and Asia-Pacific are clustering within a short announcement window. The pace of ex-U.S. AI factory buildout is accelerating, with direct implications for global GPU allocation and supply chain concentration.

  • P2 AMD: Over $10 Billion in Taiwan Ecosystem Investment

    AMD announced more than $10 billion in Taiwan ecosystem investment commitments targeting AI infrastructure supply chain and manufacturing.

    The read: Both major GPU/CPU vendors are deepening supply chain concentration in Taiwan through the TSMC relationship. At $10 billion-plus, the scale of AMD's commitment mirrors NVIDIA's infrastructure expansion trajectory.

  • P2 Oracle and NVIDIA: Agentic AI Inference Integration

    Oracle and NVIDIA announced integration between NVIDIA's accelerated computing and inference stack and Oracle's AI infrastructure and generative AI services.

    The read: Enterprise cloud providers integrating NVIDIA's inference stack natively reduces friction between hardware procurement and production deployment. This is a supply-side signal for enterprise AI adoption velocity.

Hardware and Error Correction

  • Sudden death of entanglement, rebirth of magic

    Local Markovian noise cannot bring entanglement back, but it can bring magic back. Unlike separability, stabilizer membership is not preserved by local channels, allowing dissipation to push states out of the stabilizer polytope as well as in. Under local amplitude damping, the n-qubit GHZ family α|0^n⟩+β|1^n⟩ (0<α<β) loses its magic at a lower damping stre...

  • Quantum Batteries in two-dimensional material-based Josephson Junctions

    We investigate the solid-state implementation of a Dicke-like quantum battery consisting of a two-dimensional material-based Josephson junction inductively coupled to a resonator, using graphene as a representative example. In this configuration, Andreev bound states naturally act as non-interacting, energetically non-degenerate two-level systems, and the setup allows for bo...

  • Long-range nonstabilizerness of topologically encoded states from mutual information

    We study long-range nonstabilizerness (LRN), namely the obstruction to remove nonstabilizerness with shallow-depth local quantum circuits. In one-dimensional settings, the mutual information between disconnected spatial regions has proven to be a powerful tool to diagnose LRN. In this work, we focus on encoded states of two-dimensional topologically-ordered systems, and expl...

  • Ratchet Universality and optimal suppression of shot noise in biharmonically-driven tunnel junctions

    This Letter discusses two retrodictions of the law of ratchet universality which explain previous numerical and experimental results concerning the diode effect in conventional superconducting tunnel-junctions in one case, and controlled suppression of electron-hole pair generation in a tunnel junction in the other, both in the presence of biharmonic driving fields. Our stud...

  • The relative entropy of magic and its nonadditivity

    In most stabilizer-based quantum computing schemes, so-called magic states are a necessary resource for implementing non-transversal quantum gates. With the resource theory of magic, it is possible to analyze and quantify the generation of the non-stabilizer states. The relative entropy is a measure used in various resource theories. For single qubits, we characterize magic...

  • Quasinormal mode quantization of bound and propagating photons in complex lightguiding nanostructures for integrated devices

    Open optical or plasmonic resonators are placed on and connected through surfaces or via waveguides, forming complex lightguiding nanostructures, e.g. for integrated photonic quantum devices. We derive general boundary conditions for quasinormal modes that account for the structure's specific geometry. We then present a general quantization scheme for multiple, interacting q...

  • Electron modulation and ultrafast near-field imaging with vectorial laser fields

    Controlled interaction of laser light with electron beams is fundamental for ultrafast electron microscopy and electron-based quantum optics, yet their direct coupling is forbidden in free space. Here we use longitudinally polarized light at a thin membrane and show that the emerging focal fields can modulate the electron beam in a direct, coherent and linear way, without th...

  • Symmetry Breaking as Quantum Gate: Entropy and Weak Mixing Angle

    We establish a correspondence between two independent entropic probes -- the variation of Rényi mutual information (RMI) across the electroweak symmetry breaking (EWSB) transition and the stabilizer Rényi entropy (SRE) -- in tree-level 2→2 elastic scatterings. After angular averaging, the RMI (helicity basis) and the SRE (fixed beam basis) exhibit identical dependence o...

Control and Quantum-AI Integration

  • Bottom-up open EFT for non-Abelian gauge theory with dynamical color environment

    We develop a bottom-up open effective field theory (EFT) for non-Abelian gauge theories within the Schwinger--Keldysh formalism. Instead of integrating out the environment completely and starting from a nonlocal influence functional, we retain the slow environmental response variables explicitly and construct a local system-environment EFT. The environmental sector is descri...

  • Optimal work extraction in measurement-based quantum Otto engines: Non-adiabaticity and generalized measurements can be beneficial

    Measurement-based quantum heat engines have attracted significant interest as alternatives to conventional thermal engines, as they replace the hot thermal reservoir with quantum measurements, thereby offering greater controllability and simpler implementation. Motivated by these advantages, we investigate a measurement-driven quantum Otto engine with a qubit working substan...

  • A Formal Basis for Quantum Cryptographic Exposure Measurement under HNDL Threat

    An adversary copies your encrypted traffic today and waits for a quantum computer to decrypt it later. How exposed are you? We show that the functional form of the answer is not merely a calibration choice -- it is structurally justified by three assumptions about adversarial production and value-decay dynamics. Under those assumptions, the HNDL compromise probability factor...

  • Reinforcement learning for ion shuttling on trapped-ion quantum computers

    Scalable trapped-ion quantum computing is commonly realized with modular chips that feature distinct zones with specific functionalities, such as storage, state preparation, and gate execution. To execute a quantum circuit, the ions must be transported between these zones. This process is called ion shuttling. To achieve reliable computation results, the shuttling process mu...

  • Factorization rule for multitime correlations in non-Markovian open quantum systems

    Experiments performed on quantum systems often measure multitime correlation functions. When quantum systems are weakly coupled to their environment, the time evolution of such correlation functions can be reduced to that of the reduced density matrix by the quantum regression theorem (QRT). While no QRT is available for general non-Markovian open quantum systems, we show th...

  • Computable lower bound of the parameterized entanglement monotone

    Although numerous measures of entanglement have been proposed so far, the calculation of a given faithful entanglement measure is a hard work since it is always involved in some optimization process. It is, therefore, important to estimate the lower bound of a given entanglement measure for an arbitrary quantum state. This results in a subject of intensive mathematical resea...

  • Q-PhotoNAS: Hybrid Quantum Neural Architecture Search Framework on Photonic Devices

    Photonic quantum computing is a promising platform for scalable quantum machine learning, but designing effective hybrid architectures remains challenging under hardware and optimization constraints. Existing approaches rely on manually tuned architectures that fail to account for the collaboration between classical preprocessing, phase encoding, and photonic circuit structu...

  • Kipu Quantum Launches Hybrid Framework to Enable Offline Inference for Quantum Machine Learning

    Kipu Quantum has released an off-line Digitized Quantum Feature Extraction (DQFE) pipeline that allows quantum-enhanced machine learning models to execute inference operations entirely on classical hardware. The architecture separates the quantum and classical processing loops, restricting quantum processor utilization to an initial, specialized training stage. By elimina...

  • How many systems can be dephased before the quantum switch becomes causally definite?

    Quantum processes with indefinite causal order -- so-called causally nonseparable processes -- can exhibit various advantages over quantum circuits with a fixed or a well-defined causal structure. A natural question is how much nonclassicality is required for a process to display causal nonseparability. Here we address this by investigating how many systems can be dephased (...

  • One-photon communication in atomic media

    We consider the problem of single-photon transmission through an atomic medium, using quantum channel fidelity to describe the resulting information loss. We find that the normalized fidelity decreases monotonically with coupling strength, establishing a performance bound for quantum communication through such media. Our results hold for several channel types and for determi...

  • Geometric Origin of the Non-Adiabaticity Parameter and Self-Limiting Instability in Driven Nonlinear Systems

    We establish that the non-adiabaticity parameter has a direct geometric interpretation as the instantaneous evolution speed of a driven quantum state in projective Hilbert space under the Fubini Study metric. In contrast to conventional asymptotic approaches, the proposed framework provides a strictly local geometric criterion that allows non-adiabatic instability and its no...

  • Adiabatic Quantum Phase Estimation

    Quantum phase estimation (QPE) is a central algorithmic primitive that estimates eigenvalues of a Hamiltonian up to precision ε in Heisenberg-limited time T=Θ(1/ε). Standard gate-based implementations of QPE require deep controlled time-evolution circuits and are not native to analog hardware. Here, we present a simple adiabatic protocol for QPE that achieves (up to loga...

  • A sharp interaction-degree threshold for simulating QAOA

    We identify a sharp interaction-degree threshold for the classical simulation of QAOA with $2$-local cost functions. At degree $3$, classical sampling from depth-$1$ QAOA with small multiplicative error would collapse the polynomial hierarchy to its third level. At degree $2$, exact classical sampling from depth-p QAOA on n qubits runs in time n^(O(1)) whenever $p = O(...

  • Quantum circuit design via dynamic Pauli constraints

    We introduce a novel software-oriented model of quantum computation motivated by the practical constraints of near-term quantum hardware. In this model, gates are specified by constraints expressed in terms of Pauli observables, with each disjoint layer of gates accompanied by a pairwise or k-local quantum state tomography of the device. We prove that the model is equivale...

  • Self-testing of exact entanglement embezzlement

    We consider bipartite exact entanglement embezzlement with a catalyst state vector ψ in a Hilbert space H using unitaries (or more generally, contractions). If M ⊆B(H) is a von Neumann algebra and U ∈M_d ⊗M and V ∈M' ⊗M_d are unitaries (or more generally contractions), then suc...

  • Practical Countermeasure Against Attacks Exploiting Detection Efficiency Mismatch in Quantum Key Distribution

    We demonstrate a practical countermeasure against a well-known class of attacks on quantum key distribution (QKD) systems that exploit detection efficiency mismatch, where the receiver's detectors do not exhibit identical responses to incoming photons across all degrees of freedom. This class of quantum hacking strategies is broad and significantly includes the time-shift at...

  • Entanglement Dynamics across a Monitored Quantum Point Contact

    We compute the entanglement dynamics across a monitored quantum point contact, where particle losses are recorded on a given site, and demonstrate how this single-site local monitoring substantially reshapes the entanglement production. Contrary to the unitary case, where entanglement entropy grows logarithmically in time, here we find first a linear growth, up to a maximum...

  • Joint Unitarity and a Single Definite Outcome in a Quantum Measurement

    We investigated the possibility that a single measurement run with a definite outcome is a joint unitary evolution of all the participating systems, and measurement runs with different definite outcomes correspond to different unitary maps. With reasonable assumptions, we derived a lower bound of the dependence of the environment after measurement on the state of the system...

  • Reduced Dynamical Maps in Finite Temperature Vibronic Coupling Models via Choi Matrices: Numerical Methods and Applications

    We present a streamlined implementation of a computational framework for constructing and analyzing reduced dynamical maps for complex system--bath models at finite temperature. The methodology is based on three established ingredients of quantum dynamics: the Choi--Jamiołkowski isomorphism for the representation of quantum channels, thermofield (TFD) purification of thermal...

  • Minimal Permutation-Invariant Qudit Codes from Edge-Colorings of Complete Graphs

    We study permutation-invariant quantum codes in the symmetric subspace Sym^n(C^q) of n qudits of local dimension q. For every integer q≥2, we construct a permutation-invariant code with parameters ((4,q,2))_q. Thus four physical qudits suffice to encode one logical qudit with distance two in the symmetric sector for every local dimension. We...

  • QuCtrl-BELL: A Compiler-Driven Sub-Microsecond Feedback Control Stack for Scalable Trapped-Ion Quantum Experiments

    As trapped-ion quantum computing scales to larger qubit registers and more complex control protocols, classical control systems face a fundamental tradeoff: sub-microsecond board-level feedback requires tight hardware coupling, whereas maintainability and extensibility require clean, modular software abstractions. This paper presents QuCtrl-BELL (Bell), a compiler-driven sof...

  • Dual wavelength source of entanglement for space quantum communication

    We report the demonstration of a bulk, intrinsically phase-stable source of polarization- and time-energy-entangled photon pairs at 810nm and 1550nm, directly coupled into single-mode optical fibers. This highly non-degenerate wavelength combination is well suited for hybrid quantum communication networks, enabling low-loss transmission in optical fibers at 1550nm while main...

  • Shielded inner-shell transitions in atomic samarium for tests of fundamental physics

    Forbidden atomic transitions provide some of the most stringent low-energy tests of physics beyond the Standard Model, with sensitivity set by the interplay between the sought-for signals and systematics suppressed by symmetry. Here we identify the previously unobserved 4f^66s^2 ^5D_0 level of neutral samarium at 14 564.90(2) cm^(-1), opening the...

  • Modular Variables and the Limits of Phase Detectability in Open Quantum Systems

    Modular variables serve as a striking example of quantum nonlocality, particularly in superpositions of wave packets that are spatially well separated, where the relative phase between components cannot be accessed through conventional local measurements. In this work, we explore the time evolution of Hermitian modular operators for Gaussian wave-packet superpositions under...

  • Emulation of Optically Interconnected Quantum Data Centers Topologies for Cost-Fidelity Benchmarking

    We emulate optically interconnected quantum processors in ring, star, and line topologies using a quantum computer. GHZ benchmarks show that the star provides the best trade-off between cost and fidelity under transduction and fiber noise.

  • Statistical Interpretation of the Procedures Measurement of Physical Quantities

    This work develops a conceptual framework for the foundations of quantum physics, linking two main approaches: the algebraic formulation and quantum probability. Rather than proposing new axioms or theories, the text reorganizes and synthesizes existing models, highlighting their assumptions, conceptual structures, and operational significance. The analysis begins with von N...

  • Geometric Construction of Optimal Teleportation Witnesses

    Not all entangled states are useful for quantum teleportation. We present a geometric method to construct optimal teleportation witnesses, which provide operational necessary and sufficient criteria for identifying the teleportation usefulness of arbitrary two-qudit entangled states. Specifically, by developing a two-layer iterative cutting-plane algorithm to solve the short...

  • Three sins against physics by an exaggerated quantum information perspective

    I point out three ways in which the perspective of quantum information may lead to distorted claims about physics: forgetting that light does not need to be quantised to show coherence; ignoring the generators of unitary evolutions; and approaching the discovery of nature as a fight against an adversary.

  • Unified entropy entanglement

    The unified entropy as a promotion of the von Neumann entropy exhibits distinct diversity which contains the Tsallis entropy, the Rényi entropy, the von Neumann entropy as special cases. The unified-(r,t) entropy entanglement with $0

  • Sensitivity Evaluation of SU(1,1) Interferometers with Arbitrary Input Probe State and Homodyne Detections

    We provide a general theoretical derivation of the phase sensitivity achieved by SU(1,1) interferometers under homodyne detection. The general expressions obtained accommodate arbitrary input states and include internal and external losses. In this systematic review, both full SU(1,1) interferometers with two parametric amplifiers and the truncated interferometers with only...

  • Realizing tunable non-Hermitian skin effects in dynamical quantum systems via the relative phase between multiple time-periodic driving

    We demonstrate how the relative phase between the multiple time periodic driving can decide the emergence and the favorable localization direction of non-Hermitian skin modes. For the static non-Hermitian quantum chain with parity time symmetry, non-Hermitian skin effects (NHSEs) can be prohibited. As the dynamical driving is turned on, NHSEs get artificially reactivated, wh...

  • Nonclassical Cutoff Fluctuations in Squeezed-Light-Driven High-Harmonic Generation

    Strong-field high-harmonic generation (HHG) is conventionally described semiclassically, with the driving laser treated as a classical field. This approximation becomes insufficient in nanoscale interaction geometries, where extreme spatial confinement raises the vacuum-field amplitude to the ~10^-2 level relative to the driving-field amplitude. When the quantum fluctuations...

  • Multi-Modal Spectroscopy Theory for Ultrafast Control of Rabi Oscillations

    We propose a three-cavity scheme to realize full control of the emitter-cavity coupling strength in cavity quantum electrodynamics (cQED). The involvement of coupled oscillators gives rise to transient dynamics comprising multiple spectral components, which significantly increases the numerical cost to resolve the fluorescence spectrum in the time domain. A generalized senso...

  • A2QTGN: Adaptive Amplitude Quantum-Integrated Temporal Graph Network for Dynamic Link Prediction

    Dynamic link prediction is important for modeling evolving interactions in complex systems, including social, communication, financial, and transportation networks. Classical temporal graph models capture sequential dependencies, but they may struggle to represent concurrent and rapidly changing node-edge interactions in large dynamic graphs. We propose A2QTGN (Adaptive Ampl...

  • Phase-tunable remote nonreciprocal charging in waveguide QED

    Remote quantum batteries require directional and controllable energy transfer between spatially separated quantum nodes, yet most existing protocols rely on direct charger-battery Hamiltonian couplings. Here we propose a phase-tunable waveguide-QED architecture for remote quantum-battery charging, in which a driven charger and a remote battery are coupled solely via engineer...

  • Dissipation-Selected Resonant Fronts in a Driven-Dissipative Bose-Hubbard Lattice

    Spatially structured dissipation organizes driven quantum matter beyond Hamiltonian control. We show that a dissipation gradient combined with a Stark-induced detuning ramp selects a nonlinear resonance slice in a two-dimensional driven-dissipative Bose-Hubbard lattice, producing a pinned density front in generalized Gross-Pitaevskii simulations. The underlying resonance con...

  • Photon Anomalous Blockade in Waveguide Cavity QED with Atomic Mirrors

    Waveguide cavity quantum electrodynamics (QED) with atomic mirrors is a growing research area of quantum optics and can be applied to quantum information processing. We here study the photon statistics of output fields from a waveguide cavity QED system, in which the waveguide is coupled to quantized mirror atoms and one driven medium atom. Our results show that the photon b...

  • Device-Independent Quantum Secret Sharing Protocol Enhanced by Advantage Distillation

    Device-independent quantum secret sharing (DI-QSS) provides high security by eliminating the need to trust devices, yet its practical performance is limited by channel loss and noise. This work extends advantage distillation from two-party quantum key distribution (QKD) to three-party DI-QSS, redesigning the corresponding data interaction and verification procedures. The tec...

Data Center Power Demand

  • Data center server energy use grows across the commercial building stock

    In the Annual Energy Outlook 2026 (AEO2026), our long-term outlook, we project electricity consumed by data center servers will increase across the commercial building stock, increasing more in standalone data centers than in all other data center rooms combined. By 2050, server consumption alone reaches between 446 billion kilowatthours (BkWh) and 818 billion BkWh. The high...

  • Commercial electricity sales have soared in Virginia, driven by data centers

    Commercial electricity sales in Virginia increased by nearly 30.0 million megawatthours (MWh) between 2019 and 2025, much faster growth than in any other state except Texas, a much larger state, according to our Annual Electric Power Industry Report. The growth in sales of electricity in Virginia is largely driven by a concentration of data centers, as well as electric vehic...

  • Small modular reactors and microreactors under development in the United States

    Electric utilities in the United States currently operate about 98 gigawatts (GW) of nuclear generating capacity, but very little nuclear capacity has been built in the last few decades. High capital costs and lengthy licensing and approval processes have limited the expansion of nuclear power. However, several companies are developing new small modular reactor (SMR) designs...

  • U.S. coal-fired generating capacity retired in 2025 was the least in 15 years

    During 2025, the U.S. electric power sector retired 2.6 gigawatts (GW) of coal-fired generating capacity at four power plants, the least since 2010. At the beginning of 2025, coal plant operators had planned to retire 8.5 GW of capacity; however, 4.8 GW of planned retirements were delayed to a future year, and the operators of two coal plants (1.1 GW) cancelled plans to reti...
