Operator brief

  1. Sovereign AI infrastructure is entering a procurement phase.

    France, Saudi Arabia, Taiwan, and multiple European nations have each formally committed to NVIDIA Blackwell deployments or state-backed AI factories within the current reporting cycle. Organizations planning regional AI infrastructure should expect pricing and availability pressure on DGX B200 systems. [rising]

  2. Quantum hardware manufacturing is becoming a discrete supply chain segment.

    GlobalFoundries' new Quantum Technology Solutions unit, concurrent U.S. Department of Commerce engagement on onshore fabrication, and France's additional €1B signal that quantum chip demand is approaching commercial scale earlier than most forecasts assumed. [rising]

  3. Grid capacity constraints are measurable and worsening.

    Virginia's data center load drove a 30M MWh increase in commercial electricity in six years; combined with the lowest US coal retirement rate since 2010 (2.6 GW retired against 8.5 GW planned), power availability is shaping up as the binding constraint on AI factory siting in the 2027-2030 window.

Quantum

  • P1 France Adds €1B to Quantum Plan; NVIDIA's NVentures Invests in Alice & Bob

    French state quantum funding now totals approximately €3.3B since 2021. Alice & Bob, a photonic cat-qubit startup, expanded its Series B with investment from NVIDIA NVentures alongside the policy announcement.

    The read: NVIDIA's investment arm entering quantum hardware suggests AI-compute players are hedging on near-term quantum-classical hybrid workloads. The French state commitment functions as de-risking for private follow-on capital.

  • P1 GlobalFoundries Launches Quantum Technology Solutions Unit

    A dedicated commercial fabrication division for quantum hardware developers is now active at GlobalFoundries, with concurrent U.S. Department of Commerce involvement noted.

    The read: An established-node foundry partner entering dedicated quantum chip production reduces a key bottleneck for hardware startups previously relying on academic or bespoke fabs. Onshore U.S. fabrication capacity becomes a near-term differentiator in procurement conversations.

  • P2 Flatiron Institute Classical Algorithm Refutes Historical D-Wave Supremacy Claim

    Physicists at the Simons Foundation's CCQ and Boston University published a tensor network algorithm in Science that simulates 3D quantum dynamics previously considered classically intractable, overturning a high-profile quantum advantage claim.

    The read: This does not invalidate quantum computing broadly, but it narrows the verified set of problems constituting demonstrated quantum advantage. Benchmarking claims should now incorporate updated classical simulation baselines.

  • P2 Non-Local TLS Defects Couple Two Distant Superconducting Qubits

    Researchers identified a coherent two-level system (TLS) defect residing in a substrate connecting element that simultaneously couples two spatially distant superconducting qubits, producing correlated decoherence across both.

    The read: Correlated decoherence from a shared substrate defect is a harder engineering problem than independent qubit noise. Surface-code error correction models that assume uncorrelated noise may undercount real-world failure rates when TLS defects are present in shared structures.

Chips

  • P1 AMD EPYC "Venice" Enters Production on TSMC 2nm

    AMD confirmed a production ramp for its next-generation EPYC server processor on TSMC's 2nm process node.

    The read: 2nm production confirmation for server CPUs establishes TSMC N2 yield viability at commercial volume, which is a reference data point for other AI chip designers targeting the same node in 2026-2027.

  • P2 AMD Commits More Than $10B in Taiwan Ecosystem Investments

    AMD announced investments exceeding $10B in the Taiwan ecosystem to accelerate AI infrastructure development.

    The read: The scale signals AMD's intent to deepen supply chain relationships for AI chip production beyond existing foundry agreements; likely encompasses TSMC capacity reservations, CoWoS advanced packaging, and HBM supply commitments.

Power

  • P1 EIA AEO2026: Data Center Server Electricity Could Reach 446-818 BkWh by 2050

    The U.S. Energy Information Administration's Annual Energy Outlook 2026 projects server-only electricity consumption growing to between 446 and 818 billion kilowatthours by 2050, with standalone data centers growing faster than distributed data center rooms.

    The read: The high scenario implies data center servers alone could consume roughly 15-20% of current US total electricity production by mid-century. Grid, generation, and transmission investment decisions made this decade will be sized against this range.

  • P1 Virginia Commercial Electricity Up ~30M MWh from 2019 to 2025, Led by Data Centers

    Virginia's commercial electricity sales grew by nearly 30M MWh in six years, driven primarily by data center concentration, according to EIA's Annual Electric Power Industry Report. This growth rate exceeded all other states except Texas, which is a much larger state.

    The read: Northern Virginia is already operating near the edge of regional grid capacity. Any operator selecting a Mid-Atlantic data center site should factor interconnection queue delays and potential load deferral requirements into their planning timeline.

  • P2 ERCOT Solar Forecast to Exceed Coal Generation for First Time in 2026

    EIA's Short-Term Energy Outlook forecasts 78 BkWh of utility-scale solar in ERCOT in 2026, which would surpass coal-fired generation on an annual basis for the first time.

    The read: An accelerating solar share changes the shape of the wholesale power price curve in Texas. For data center operators with interruptible load agreements or on-site storage, this shifts the value calculation for flexible load and battery positioning.

  • P2 US Coal Retirements in 2025 Lowest Since 2010 as Operators Defer Exits

    Only 2.6 GW of coal capacity retired in 2025 against a planned 8.5 GW; 4.8 GW of retirements were pushed to future years, and operators cancelled retirement plans for 1.1 GW.

    The read: Coal retirement deferral is partly a response to data center demand growth straining grid reserves in affected regions. This delays the grid's transition to lower-carbon baseload and extends dispatch cost volatility in markets where coal sets the price floor.

AI Compute

  • P1 NVIDIA Germany AI Factory: 10,000 GPUs for European Industrial Workloads

    NVIDIA announced construction of a Germany-based AI factory featuring 10,000 GPUs, including DGX B200 systems and RTX PRO Servers, intended for European manufacturing applications.

    The read: The DGX B200 and RTX PRO combination targets simulation, digital twin, and design workloads rather than large-scale training alone. This positions the factory as a mixed inferencing and engineering compute facility rather than a pure LLM training cluster.

  • P1 Europe Blackwell AI Infrastructure: Multiple Nations Committing to Sovereign Deployments

    NVIDIA announced coordinated Blackwell infrastructure commitments with European nations, technology leaders, and industry partners aimed at digital sovereignty and industrial AI competitiveness.

    The read: The pattern -- sovereign governments co-investing in GPU-vendor-specific AI factories -- reduces NVIDIA's commercial risk on Blackwell capacity while creating multi-year hardware dependencies at the national level. Digital sovereignty goals and vendor lock-in are becoming structurally linked.

  • P2 Saudi Arabia's HUMAIN and NVIDIA Announce AI Factory Partnership

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

    The read: The PIF/HUMAIN structure suggests Saudi Arabia is building state-controlled AI compute capacity rather than purchasing hyperscaler cloud access. This is a sovereign infrastructure play that creates a distinct procurement channel from commercial cloud agreements.

  • P2 Foxconn and Taiwan Government Build Blackwell AI Factory Supercomputer

    NVIDIA and Foxconn Hon Hai Technology Group announced a partnership with the Taiwan government to build an AI factory supercomputer delivering Blackwell infrastructure for researchers, startups, and industries.

    The read: Foxconn's manufacturing depth combined with proximity to TSMC creates an integrated supply-and-deployment loop. This facility may serve as a reference architecture for AI factory construction given its embedded hardware supply chain advantages.

Hardware and Error Correction

  • Time crystals in cavity-BEC systems

    The understanding of light-induced dynamical states continues to be a challenging and fruitful pursuit of science. This pursuit is supported by quantum simulation of dynamical phenomena, e.g., in ultracold atom systems. Typically, ultracold atom dynamics are read out destructively, via time-of-flight imaging, limiting a detailed analysis. However, atom-cavity systems provide...

  • Complementing Quantum Error Correction in Quantum Metrology via Swap Test

    The precision and sensitivity achievable in quantum metrology are often compromised by the presence of noise. While quantum error correction has emerged as a promising strategy, it is ineffective in addressing noise that is indistinguishable from the signal. To address this challenge, virtual state purification was introduced as a complementary approach to quantum error corr...

  • Optimizing Parallel Execution of Commuting Pauli Product Rotations

    Fault-Tolerant Quantum Computation (FTQC) permits parallel execution of mutually commuting Pauli Product Rotations (PPRs), but per-qubit access point/port limits (e.g. two X and two Z edges on the surface code) force commuting groups that exceed the budget to be split, inflating circuit depth. We propose two heuristics for reducing this hardware-limited depth: 1. clique resh...

  • Atom-Photon Bound States in Fractal Photonic Lattices: Localization Length and Anomalous Diffusion

    We study atom-photon bound states seeded by two-level emitters coupled to self-similar photonic lattices. By expressing the photonic Green's function through the heat kernel, we show that the far-field localization length obeys ξ~Δ^(-1/d_w), with the detuning Δ from the lower spectral edge and the walk dimension d_w of the underlying fractal. This scaling is contro...

  • Multiphoton heralding generates large-amplitude squeezed Schrödinger cat states and parity-selective Fock superpositions from squeezed vacuum via an OPA

    We propose a multiphoton heralding scheme using an optical parametric amplifier (OPA) that converts squeezed vacuum into two families of non-Gaussian states: large-amplitude squeezed Schrödinger cat states and low-order parity-selective Fock superpositions. By injecting m photons into the idler port and detecting n photons at the output, effective high-order photon subtracti...

  • Asymptotic Limits of Entanglement Distribution

    Reliable distribution of quantum entanglement over long distances is a central challenge in quantum information science, fundamentally limited by decoherence in noisy communication channels. In this work, we investigate the asymptotic limits of entanglement distribution across quantum networks utilizing intermediate repeater stations and local operations and classical commun...

  • Hybrid Quantum-Classical Corrective Diffusion Modeling for Meteorological Downscaling

    Statistical downscaling is a crucial component of the weather modeling field, where high-resolution outputs must be reconstructed from coarse-resolution inputs with the full cost of dynamical refinement. In this work, we investigate a hybrid quantum-classical corrective diffusion model for probabilistic statistical downscaling of weather fields. The proposed model inserts va...

  • Modeling the Quantum Photon Statistics in Hybrid Light-Matter Integrated Circuits

    Strong light-matter coupling between a guided electromagnetic mode and an excitonic semiconductor transition gives rise to exciton-polaritons with optical nonlinearities far exceeding those of conventional photonic platforms. Utilizing these nonlinearities in the few-particle regime, where quantum signatures such as photon antibunching, sub-Poissonian statistics and non-triv...

Control and Quantum-AI Integration

  • Convexity and non-Markovianity of Weyl Maps

    We investigate the emergence of non-Markovian dynamics in finite-dimensional open quantum systems governed by Weyl dynamical maps and their convex combinations. Using the Hermite normal form, we provide a complete classification of the subgroups of the discrete phase space Z_d ×Z_d, establishing the algebraic framework underlying the Weyl maps. We c...

  • Non-Local and Non-Markovian Effects of a Microscopic Two-Level Defect in Superconducting Quantum Circuits

    Microscopic two-level systems (TLS) -- ubiquitous atomic-scale defects in solid-state quantum devices -- are a dominant source of qubit decoherence, yet their role is often considered local and short-memoried. Here, we report the observation of a coherent TLS that couples simultaneously to two spatially distant superconducting qubits. The TLS is identified to reside within t...

  • SAFE ma-QAOA: Surrogate-Assisted and Fine-Tuning Enhanced Multi-Angle QAOA with Parameter Distillation

    The multi-angle Quantum Approximate Optimization Algorithm (ma-QAOA) extends the Quantum Approximate Optimization Algorithm (QAOA) by assigning a larger number of independent variational parameters, thereby increasing expressivity and improving performance at low circuit depths. However, this larger parameterization makes training more difficult and requires repeated circuit...

  • Enhancing Blood Cells Classification using Hybrid Quantum Neural Networks

    Accurate classification of microscopic blood cells is still a critical task in medical image analysis, where subtle variations and limited data can challenge conventional deep learning models. As such, we investigate in this work the potential of Hybrid Quantum-Classical Neural Networks (HQNNs) to enhance feature representation and improve classification performance in this...

  • Local-Observable-Guided Generative Quantum Circuits for Degenerate Ground Spaces

    Searching for degenerate ground spaces in quantum many-body systems is central to understanding spontaneous symmetry breaking and topological order. Although existing numerical methods can approximate individual ground states with high accuracy, recovering the full degenerate space remains a substantial challenge. Here we tackle this problem using a hybrid generative quantum...

  • A Two-Branch Finite-Field Construction for Regular CSS LDPC Bases

    This paper develops a two-branch multiplicative-coset construction for regular Calderbank-Shor-Steane (CSS) quantum low-density parity-check base matrices. For a target column weight J and an even row weight L, the method reduces regularity, CSS orthogonality, and same-type 4-cycle exclusion to explicit quotient-coset conditions over a finite field. A normalized exha...

  • Not all black holes decohere quantum superpositions

    We study the decoherence induced by near-extremal charged black holes on quantum systems in their exterior. Specifically, we analyze a thought experiment recently discussed in the literature, where the quantum system is a charged particle prepared in a spatial superposition. Near-extremal black holes are known to exhibit large quantum metric fluctuations of the near-horizon...

  • Quantum Quenches that Resemble Operator Growth

    We study growth quenches, which are local quenches that may gradually destabilize a false vacuum in certain kinetic constrained quantum lattice models, such as the East-West model. We point out a formal analogy with the dynamics of a local operator in the Heisenberg picture. Exploiting this analogy, we obtain several results on growth quenches by adapting operator-dynamics c...

  • Coherent dynamics in chaotic spin chains via interference-protected subspaces

    Generic quantum many-body systems are expected to thermalize, scrambling initial coherence while local observables relax to equilibrium values. Weak ergodicity breaking, often associated with quantum many-body scarring of homogeneous states, provides rare exceptions with long-lived coherence. We introduce a family of local spin-1/2 chains with a structured subspace that host...

  • Indefinite probabilities in quantum spacetime: A deepening of unpredictability

    Non-commutative spacetime and quantum groups have been argued to capture non-classical features of spacetime and its symmetries in the low-energy limit of quantum gravity. In this letter, we show that employing the SU_q(2) quantum group to describe rotational symmetry for spin-1/2 systems and Stern-Gerlach apparatuses leads to the description of probabilities of...

  • Exact versus tight-binding models in longitudinally modulated PT-symmetric coupled waveguides

    The tight-binding (TB) model is a widely adopted approximation scheme for describing light propagation in waveguide arrays. Despite its success, its validity in PT-symmetric systems characterized by strong longitudinal modulation has not been rigorously benchmarked against exact analytical solutions. In this work, we address this gap by performing a comparative a...

  • IntegrateUnitary.jl: A Julia package for symbolic integration over Haar measures

    Symbolic integration over the Haar measure of compact groups is a computational cornerstone in quantum information science and random matrix theory. We present \texttt{IntegrateUnitary.jl}, a comprehensive Julia package for computing exact expectations of polynomial functions over a wide range of compact groups (U(d), O(d), Sp(d), and SU(d) for balanced polynomials),...

  • The negativity core of a 1+1D massless scalar quantum field

    Vacuum entanglement is a fundamental feature of quantum field theory exhibiting rich structure that is not completely understood. Here, we provide a complete characterization of the entanglement between two bounded spacelike-separated regions in a (1+1)-dimensional free massless real scalar field. Employing Gaussian state methods, we analytically compute the logarithmic nega...

  • The Floquet-Magnus expansion of unbounded operators

    The Floquet-Magnus expansion is a widely used tool to derive effective descriptions of time-periodic quantum systems by approximating their dynamics with a time-independent Hamiltonian. However, its standard formulation is, strictly speaking, restricted to bounded Hamiltonians. In this work, we extend its definition and analysis to a broad class of time-periodic unbounded Ha...

  • Noise and Configuration Recovery Impact on Quantum Selected Configuration Interaction

    Quantum-selected configuration interaction (QSCI) is a promising hybrid quantum-classical approach in which a quantum device generates configurations for subsequent classical diagonalization. Here, we analyze the performance of QSCI combined with the local unitary cluster Jastrow (LUCJ) ansatz, focusing on the interplay between ansatz expressivity, sampling, noise, and confi...

  • Twirled Perfect Tensor Networks: Computationally covariant holographic tensor networks

    We define a novel class of tensor networks motivated by the Python's Lunch Conjecture (PLC) in local tensor network models of the black hole interior. We start from the observation that, for extended black brane states with short-range correlations, the PLC predicts a complexity that is smaller than the upper bound for generic short-range correlated states. We argue that the...

  • Quantum Ghost Spectroscopy Reveals Hidden Electronic Coherence in Molecular Aggregates

    Ultrafast spectroscopy of molecular systems is fundamentally constrained by the Fourier uncertainty principle: high temporal resolution smears out electronic state signatures, while high spectral resolution obscures dynamic information. Here we overcome this limitation using time-resolved quantum ghost spectroscopy (tr-QGS) with entangled photon pairs, which enables independ...

  • Information transfer along the causal lightcone of a brickwork quantum circuit

    Understanding how local information propagates through many-body quantum systems is a central problem in nonequilibrium dynamics, with important implications for quantum communication, state transfer, and remote sensing. In this work, we investigate information transfer along a one-dimensional open chain of qudits, focusing on the task of recovering information initially enc...

  • Non-Hermitian Landau Levels

    We formulate non-Hermitian Landau levels in two-dimensional systems under a complex perpendicular magnetic field. In the symmetric gauge, we derive their discretely spaced, highly degenerate complex spectra and biorthogonal eigenstates, and clarify the role of non-unitary gauge transformations. A non-Hermitian Harper-Hofstadter lattice model confirms the continuum theory and...

  • Entanglement entropy across the dynamical phase transition in the quantum O(N) model

    We demonstrate that the dynamical phase transition of the quantum O(N) model at large N leaves universal fingerprints in the infrared structure of the entanglement spectrum. While the leading contribution to the entanglement entropy at long time follows the conventional volume law associated with ballistic entanglement spreading, its subleading behavior sharply...

  • Probing Chaos and Criticality with Observational Entropy and Finite-Resolution Measurements

    Coarse-grained measurements offer a scalable alternative to full state tomography for characterizing complex quantum dynamics. We show that observational entropy (OE), an information-theoretic entropy defined directly from finite-resolution measurement outcomes, provides a unified and experimentally accessible framework for quantifying chaos and probing criticality. From pro...

  • Quantum resource redistribution drives spectral splits in dense neutrino gases

    Whether a quantum many-body system can be efficiently simulated hinges not only on its size but also on how quantum resources are organized within it. We characterize the quantum resource landscape of collective neutrino oscillations using entanglement entropy, non-local magic, and matrix product state bond dimension. Using tensor network simulations of neutrinos in the two-...

  • CV-QKD over Turbulence Channels with Virtual Photon Subtraction and Quantum Multiple-Symbol Detection for Underwater Quantum Communications

    Continuous-variable quantum key distribution (CV-QKD) is a promising approach for secure underwater quantum communications (UQCs), where propagation loss, scattering, turbulence, and receiver thermal noise can severely degrade the transmission of quantum states. In this paper, we propose an underwater CV-QKD system with virtual photon subtraction (VPS), implemented through p...

  • Non-Maximally Entangled States for Quantum Key Distribution in Underwater Channels: BBM92 Protocol via Kraus Operators

    Underwater optical channels pose significant challenges to the security and reliability of quantum communication systems due to absorption and scattering. In this paper, we investigate the BBM92 entanglement-based quantum key distribution (QKD) protocol under realistic underwater channel conditions. Photon pairs are prepared in non-maximally entangled states, and the underwa...

  • Multi-flux Aharonov-Bohm caging with tunable couplings

    Aharonov-Bohm (AB) caging is the complete wavefunction localization effect in translational-invariant lattices induced by destructive phase interference. These phases originate from the gauge fields such as the penetrated magnetic fields, which are directly related to several novel topological quantum states of matter. Recently, this effect has demonstrated significant poten...

  • Minimal Trade-off and Optimal Measurement for Multiparameter Quantum Estimation

    A fundamental challenge in multiparameter quantum estimation arises from the incompatibility of optimal measurements for different parameters, leading to intricate precision trade-offs that obscure the understanding of ultimate quantum limits. Here, we present an approach that precisely quantifies these trade-offs for an arbitrary number of parameters encoded in pure quantum...

  • Ancilla-Efficient QSAMPLE Preparation for Reversible Markov Chains

    Preparing quantum samples (QSAMPLES), coherent encodings of stationary distributions of reversible Markov chains, is a fundamental primitive in quantum sampling, particularly for quantum simulated annealing. A central limitation of existing phase-estimation-based frameworks is the ancilla qubit overhead. In this work, we present a new end-to-end framework requiring only one...

  • Quantum Simulation of Energy Bifurcation and Z_2-Symmetry Restoration in Macroscopic Quantum Tunneling

    Macroscopic quantum tunneling (MQT), a cornerstone of Leggett's program, is deeply linked with instanton physics, yet its experimental verification remains elusive. This Perspective demonstrates that the quantum Rabi model manifests observable, instanton-like effects via quantum simulation. In the MQT regime, qubit-boson interactions drive Polyakov's energy bifurcation, gove...

  • Lowest order Carleman linearization for steady state fluid flow simulations

    It is shown that the lowest (second) order truncation of the Carleman linearization of the fluid equations (C2) recovers not only the initial transient of the time evolution but also its late stage, namely the steady-state solution. This asymptotic property is first proved analytically for the decaying logistic with external forcing and then shown to hold to a significant de...

  • Selective Fermi-Level Pinning: A Design Strategy for Giant Rectification in Molecular Junctions

    Molecular rectifiers are key functional components of molecular-scale integrated circuits, yet achieving high rectification ratios remains a longstanding challenge due to the intrinsic symmetry of resonant tunneling and the complexity of interfacial energy-level alignment. Here, we propose a rectifier design strategy based on selective Fermi-level pinning that breaks transpo...

  • A Compilation Framework for Quantum Simulation of Non-unitary Dynamics

    Most quantum compilers assume programs are reversible unitary circuits. This fits closed-system algorithms, but not open-system simulation, where the natural program objects are quantum channels describing non-unitary dynamics. We present a channel-first compilation framework that treats channels as first-class compilation objects. Our core IR, ChannelIR, represents channels...

  • Electron-Photon Spatial Entanglement in Coherent Cathodoluminescence

    Electron-photon quantum entanglement in an electron microscope paves the way for a new quantum platform, enabling the integration of quantum functionalities into electron microscopy and opening opportunities for quantum imaging and quantum sensing at the nanoscale. To realize such a platform, it is crucial to understand the degree and nature of electron-photon entanglement i...

  • On the Approximate Non-Deterministic Degree of Total Boolean Functions

    The approximate non-deterministic degree of a Boolean function f, denoted ndeg_ε(f) (written N_ε(f) for brevity), is the minimum degree of a real polynomial p such that 0 ≤|p(x)| ≤ε whenever f(x) = 0, and |p(x)| ≥1 whenever f(x) = 1. Unlike exact non-deterministic degree, which only requires the polynomial to be nonzero on $1$-input...

  • Quantum viscosity mechanism of the dissipative dynamics in the Dicke model expressed via Lindblad equation of motion

    Quantum dissipation is studied in the superradiant phase of the Extended Dicke model. It is demonstrated analytically by quantum mechanical derivation of the Lindblad equation for the Dicke model in the superradiant state coupled to Caldeira-Leggett thermal bath, that the effective viscosity appearing in the semiclassical equations of motion of polaritonic condensate survive...

  • A General Quantum Speed Limit for Non-Hermitian Systems

    The quantum speed limit (QSL) refers to the maximum speed of a quantum system to evolve from an initial state to its orthogonal states. The bound on the QSL for Hermitian systems, for example the Mandelstam-Tamm (MT) and Margolus-Levitin (ML) as well as Sun-Zheng(SZ) bound, was studied respectively from the perspectives of average value and variance of the system Hamiltonian...

  • Interference of local-measurement histories

    The evolution of a quantum system comprises two fundamental processes--continuous unitary dynamics and stochastic measurement-induced jumps. The latter are often viewed as a source of decoherence. Can two histories of such an evolution, made up of local measurements, interfere with each other? Here, we answer this question in the affirmative. A manifestation of this interfer...

  • Two Operational Principles Single Out Quantum Theory

    Quantum theory combines density matrices, Born probabilities, tensor-product composites, positive-operator-valued measures (POVMs), and quantum channels. In a finite-dimensional causal operational theory, we prove that two postulates suffice: local input-output statistics identify channels, and every state admits an equivalent-system purification, unique up to reversible dyn...

  • Coverage Analysis of Rydberg Atom Quantum Receiver Arrays: A Stochastic Geometry Approach

    Rydberg atomic quantum receivers (RAQRs) offer quantum-limited sensitivity and broadband tunability. It is not obvious whether this device-level advantage also improves network reliability, since in dense deployments, aggregate interference can push the atomic transducer out of its small-signal regime. This paper addresses the question by embedding the RAQR front end into a...

  • Anomalous Decay of Quantum Resources: The Entanglement Sudden Death Mpemba Effect

    In classical thermodynamics, the Mpemba effect refers to the counterintuitive observation that hot water can freeze faster than cold water, manifesting as an anomalous crossing of dynamical trajectories. While analogues of this phenomenon have been explored in quantum radiative systems and spin-chain entanglement asymmetry, its connection to the finite-time decoupling of qua...

    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...
