Operator brief

  1. rising

    Sovereign AI factory demand is accelerating, not plateauing. Within a single feed cycle, NAVER (55 MW initial, targeting gigawatt scale), SK Telecom (gigawatt-scale Korean AI cloud, first factory 2027), Foxconn/Taiwan, and a German industrial AI cloud (10,000 GPUs) all announced expansions on NVIDIA's DSX platform. These name specific capacity and timelines, not aspirational intent.

  2. blocker

    Power is the binding constraint on AI factory timelines ahead of GPU supply. EIA's AEO2026 projects U.S. data center server electricity at 446-818 BkWh/year by 2050; Virginia's grid already registered +30 million MWh in commercial sales from 2019 to 2025. Pipeline permitting and grid interconnect queues will gate factory online dates.

  3. rising

    AMD's Venice EPYC production ramp on TSMC 2nm adds competitive server CPU supply at the advanced node. Combined with co-packaged optics (CPO) scaling challenges -- tens of millions of units per year without standardized test methods -- the interconnect layer is emerging as the next bottleneck after power.

Quantum

  • P1 U.S. and Japan Commit $1 Billion to Joint Quantum and Advanced Computing Research

    The largest publicly reported bilateral quantum R&D commitment creates multi-year runway for hardware and fault-tolerance research.

    The read: Bilateral commitments at this scale shift academic lab priorities toward applied fault tolerance and create downstream procurement signals for hardware vendors. Watch for DOE national lab research agreements to follow.

  • P2 Dynamic 4.8.8 Floquet Code (arxiv preprint)

    A new fault-tolerant memory variant improves on the honeycomb Floquet code by raising threshold and reducing qubit overhead without halving spatial code distance.

    The read: Incremental QEC improvements matter for near-term fault-tolerant roadmaps. This class of ancilla-free dynamic code has direct relevance to superconducting hardware where physical qubit overhead drives cost.

Chips

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

    AMD has begun production ramp of its next-generation EPYC server CPU on TSMC's 2nm process node.

    The read: 2nm server CPU availability tightens competitive pressure on Intel and confirms TSMC's advanced node yields are sufficient for high-volume server silicon. Operators planning server refreshes should monitor Venice SKU availability timelines.

  • P2 Co-Packaged Optics Testing Faces Steep Data Center Ramp (SemiEngineering)

    CPO must scale to tens of millions of units per year, but the industry lacks standardized automated electrical and optical test methods.

    The read: CPO is the successor to pluggable optics for high-bandwidth AI cluster interconnects. The test gap is a supply chain risk: without agreed qualification methods, yield cycles will slow volume deployment at the moment AI factory interconnect demand peaks.

Power

  • P1 EIA AEO2026: U.S. Data Center Server Energy Reaches 446-818 BkWh/yr by 2050

    EIA's long-range outlook projects a structural transformation in U.S. electricity demand driven by data center servers, with standalone data centers growing faster than all other data center rooms combined.

    The read: The 446-818 BkWh range reflects genuine uncertainty about AI demand trajectories. Even the low case requires significant long-range grid investment. The gap between AI factory planning timelines (3-5 years) and grid infrastructure timelines (10-20 years) is the core policy risk.

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

    Data center concentration in Virginia has produced the fastest commercial electricity growth of any state except Texas over six years.

    The read: Virginia is already showing what AI factory clustering does to a state grid. As new AI factories choose sites, local grid capacity and interconnect queue position will be decisive cost factors, not afterthoughts.

AI Compute

  • P1 NAVER Expands Sovereign AI Infrastructure, Starting at 55 MW

    NAVER will build sovereign AI infrastructure beginning at 55 MW with stated plans to scale to gigawatt capacity using NVIDIA's DSX platform.

    The read: 55 MW is a concrete near-term demand data point; gigawatt scale is a planning target without a committed date. NAVER's stated rationale is serving external AI demand, not solely internal use -- meaning this is a commercially motivated infrastructure build.

  • P2 NVIDIA Builds Industrial AI Cloud in Germany (10,000 GPUs)

    NVIDIA is building a 10,000-GPU AI factory in Germany targeting European industrial manufacturers, using DGX B200 systems and RTX PRO Servers.

    The read: The vertical-specific framing (manufacturing: design, engineering, simulation, digital twins) distinguishes this from general-purpose hyperscaler builds. NVIDIA is packaging hardware plus software stacks for industrial buyers, expanding the addressable market.

  • Operation Mpemba effect: Breakdown of resource-Markovianity of free dynamics

    The Mpemba effect refers to faster relaxation of states that are initially farther from equilibrium, yet its characterization is often tied to a chosen distance or resource measure. We introduce resource-Markovianity, an extended concept of quantum Markovianity to quantum resource theories, and formulate the resource Mpemba effect operationally as the breaking of resource-Ma...

  • Who Earns the Safety? Intervention-Aware Quantum Predictive Control with Safety Attribution

    Hard safety filters are increasingly placed downstream of learned controllers to guarantee constraint satisfaction at run time. Yet a filtered controller that never violates a constraint may still have learned nothing about safety: the filter can silently repair an incompetent upstream policy, so that post-filter success measures the filter, not the policy. We argue that saf...

  • From Pauli Strings to Quantum Dynamics: A Unified Characterization

    Understanding the dynamical properties of quantum systems is an essential task in quantum computing, quantum control, and many-body physics. Tools such as representation theory and Lie theory provide crucial information on reachability and computational power. However, this information can be difficult to access exactly or compute efficiently for arbitrary generating sets. H...

  • Adaptive directional gradients for parameterised quantum circuits

    Training parameterised quantum circuits (PQCs) on quantum hardware is bottlenecked by the measurement cost of gradient estimation, which under the parameter-shift rule scales linearly in the number of trainable parameters and dominates the total shot budget of training at scale. In this work, we propose a framework of forward gradient estimators for PQCs, based on the forwar...

  • Leveraging Landau-Zener-Stückelberg interference for accelerating diabatic quantum annealing

    Diabatic quantum annealing with variationally optimized schedules can exhibit exponential speedups over conventional adiabatic quantum annealing, as was demonstrated numerically for a frustrated Ising ring model by C{ô}t{é} et al. Here we identify Landau-Zener-St{ü}ckelberg interference as the underlying mechanism for this speedup, and based on this insight we propose a vari...

  • Zermelo's navigation problem through the lens of quantum annealing: How the Landau-Zener approximation leads to an efficient classical solution

    The river-crossing problem, also known as Zermelo's navigation problem, is a classic example of an optimization problem with practical relevance and a scalable degree of complexity. It asks for the optimal trajectory of a vessel moving through a water flow field and provides a setting in which physics, variational methods, and optimization are naturally intertwined. We state...

  • Hardware-Aware QAOA for Honeypot Traffic Partitioning on 100+ Qubit IBM Quantum Processors

    Denial-of-service (DoS) and distributed denial-of-service (DDoS) mitigation requires separating malicious traffic from benign traffic while minimizing disruption to legitimate users. Prior work proposed mapping honeypot traffic partitioning to a weighted MaxCut problem and solving the resulting graphs with variational quantum algorithms. We extend this proof of principle dir...

  • Impact of gate-voltage noise on silicon spin-qubit variational quantum eigensolvers

    Quantum computers offer a route to outperform classical methods in tasks such as molecular simulation, motivating hybrid algorithms like the Variational Quantum Eigensolver (VQE) for near-term devices. Silicon spin qubits are a promising platform for scalable quantum computation, but their performance is limited by hardware imperfections -- most notably charge-noise-induced...

  • Topological defects and scalar field modes in warped geometries

    We develop a general framework for investigating the influence of topological defects on the local characteristics of a quantum scalar field in a warped geometry background. The Ricci tensor and curvature scalar are decomposed into contributions from the warp factor, the radial geometry and the angular defect structure. For an arbitrary curvature coupling parameter, the fiel...

  • Complexity-driven transitions in quantum observation

    Observing the physical world is a foundational pursuit in science. In the quantum realm, however, observation necessitates a fundamental quantum-to-classical conversion: destructive measurements irreversibly project quantum states into classical data, inevitably incurring a loss of information. What physical principles govern this information loss, and how can we construct o...

  • Quantum Cut Sparsifiers

    In this paper, we continue a line of research initiated by Basu, Brakensiek, and Putterman [2026] studying the sparsifiability of Hamiltonians. We focus particularly on the sparsifiability of the widely-studied Quantum Cut (QC) Hamiltonians. Our main result is that in an n-qubit system, any n-qubit QC Hamiltonian can be sparsified to O(n /ε^2) man...

  • Sambe Approach to Floquet-Lindblad Open Quantum Systems

    We study driven and open quantum systems described by a time-periodic Lindblad master equation. In closed systems, the stroboscopic dynamics can always be described by an effective time-independent Floquet Hamiltonian; this idea is the basis of Floquet engineering. However, in the presence of dissipation, the existence of an effective time-independent Floquet Lindbladian is...

  • A Bell-State Extension of Loop-Back Quantum Key Distribution

    Bidirectional quantum key distribution (QKD) protocols face persistent challenges related to classical disclosure, confinement of the signal space to predictable subspaces, and limited detectability under substitution or entanglement-swapping attacks. In this work, we present a Bell-state extension of the Loop-Back QKD architecture that improves efficiency and detectability...

  • Optomechanically controlled response amplification for enhanced quantum sensing

    We show that strongly amplified dynamical responses in cavity optomechanical systems can be harnessed for enhanced quantum sensing. By tuning the optomechanical interaction to a regime of enhanced susceptibility, weak perturbations produce disproportionately large changes in the system response, leading to substantially improved estimation precision. Using Gaussian estimatio...

  • Analog quantum simulation of chiral magnetic dynamics using optical superlattices

    We propose an analog quantum simulation of chiral magnetic dynamics using ultracold atoms in an optical superlattice. The massive Schwinger model in the zero gauge coupling limit maps onto the Rice-Mele model, with the fermion mass and topological angle encoded in the superlattice parameters. We study the real-time dynamics of the vector current following two quench protocol...

  • Parahydrogen Cooling of Nuclear Spin Chains at Hypogeomagnetic Fields

    Solution-state molecular nuclear spin networks are promising quantum simulators because their scalar-coupling Hamiltonians are chemically programmable, precisely measurable, and coherent at room temperature. Their main limitation for quantum information science is initialization: thermal Boltzmann polarization produces highly mixed, high-entropy states. Here, we use parahydr...

  • Phase-only control of GRAPE shaped pulses

    We compare phase-only control with phase-and-amplitude control when designing shaped pulses using the GRAPE algorithm, and explain why phase-only control has significant advantages. Trotterisation can be used to simulate amplitude modulation with phase modulation, indicating that the two approaches are fundamentally equivalent. Pulses designed by either method can be interco...

  • Quantum Algorithms for Modulated Circulant Matrix Vector Multiplication

    Modulated circulant matrices form a special class of N-parametric circulant matrices, recently introduced in the literature, with a structured spectral decomposition based on a Vandermonde type basis. Motivated by this definition, in this work we define the Modulated Quantum Fourier Transform (MQFT), a quantum primitive tailored to this matrix family.

  • Entanglement Generation through Coherent and Non-Coherent Control

    The controlled generation of quantum entanglement from separable states remains a central challenge in quantum information science. Here, we investigate entanglement generation using two related control paradigms: coherent path superposition of local unitary operations and stochastic implementations of Pauli channels under coherent control. We show that entangled states belo...

  • Conceptual and Geometric Foundations for a Teleparallel Approach to Quantum Gravity

    We revisit quantum field theory in curved spacetime (QFTCS) as a semi-classical framework for quantum matter on classical geometries, emphasizing its limitations, including vacuum ambiguity and background dependence. We briefly review major approaches to quantum gravity (QG), including Loop Quantum Gravity (LQG), string theory, and asymptotic safety, highlighting their conce...

  • Probabilistically Checking Quantum Proofs, with Interaction

    The model of interactive oracle proofs (IOP) generalizes the notion of probabilistically checkable proof (PCP), in which a static proof is verified probabilistically by querying a small number of bits, to the interactive setting: a polynomial-time verifier interacts with an unbounded prover, but is restricted to only reading a small number of bits, in total, from the message...

  • Algebraic Kolmogorov--Arnold representation theorem for quantum measurement

    We establish an operational framework connecting the classical Kolmogorov--Arnold (KA) representation theorem to quantum information theory. By introducing and proving an algebraic, bounded-degree polynomial version of the theorem, we demonstrate that any target physical property of an unentangled multi-qubit product state can be exactly decomposed using a finite, fixed set...

  • Single plasmon transport in one dimensional nanowire

    We introduce a unified theoretical framework for single-plasmon transport in one-dimensional nanowires, bridging the quantized electromagnetic Green's tensor formalism with effective non-Hermitian Hamiltonian models. This approach naturally incorporates propagating surface plasmon polaritons, high-order modes dissipative channels, and intrinsic losses. We investigate both th...

  • Strong-field control of the Z-boson resonance in e^+e^- collisions

    Resonant Z-boson production is a cornerstone of precision electroweak physics, with its vacuum line shape set by the Z mass, width, and collision kinematics. We show that a strong laser field can significantly alter this picture. By treating the field nonperturbatively, we find that laser dressing of the incoming fermions alters the effective collision kinematics and ope...

  • Classical Stochasticity Using Quantum Computers

    We suggest that quantum algorithms can be used to model classical stochastic simulations as the measurement process is inherently random. To illustrate, we solve the classical Lorenz system with stochastic behavior using a Python random number generator. We compare the classical stochasticity of the Lorenz system with the measured output of the system obtained using quantum...

  • Energy Transport in Randomly Coupled Quantum Systems: A Perturbative Approach

    We study energy transport between two quantum systems coupled through a random interaction. The central feature of our approach is to model the coupling as a Gaussian random matrix, which enables a simple and systematic perturbative expansion. In the large-N limit, we derive explicit expressions for the energy transfer rate and heat conductance up to second order in the co...

  • Range-controlled entanglement in Lindbladian skin states of monitored fermions

    Reservoir engineering can stabilize states inaccessible to unitary dynamics. Directed particle-conserving dissipation creates Lindbladian skin states, where Pauli exclusion turns edge accumulation into a many-body density imbalance. In a monitored fermion chain with tunable hopping range, we identify, within a Gaussian trajectory approximation, two finite-size scaling regime...

    Quantum Key Distribution (QKD) has emerged as a fundamentally secure approach to communication in the era of quantum computing, offering protection against threats posed to classical cryptographic schemes such as RSA and Diffie-Hellman. This thesis presents a comprehensive performance analysis of satellite-based QKD protocols, focusing on both prepare-and-measure and entangl...

  • Dynamic scaling and Family-Vicsek universality in the Hubbard model at infinite temperature

    We study Family-Vicsek scaling of charge, spin, and energy fluctuations in the one-dimensional Hubbard model at infinite temperature. Using a quantum generating function approach, we compute time-dependent cumulants of transferred conserved quantities and analyze how the corresponding roughness depends on subsystem size and time. We start by focusing on a single interface at...

  • The Transformation-Response Framework: An Operational Reformulation of Quantum Mechanics

    We present the transformation-response framework, an operational reformulation of quantum mechanics. A quantum state is not a Hilbert space object but the catalog of a system's responses to all physical transformations: for each operation g from the system's local group G, an interference experiment gives a complex value χ(g). The collection {χ(g): g∈G } is the...

  • Controlling multiparameter quantum estimation in exciton-optomechanics system

    Multiparameter quantum estimation has emerged as a central task in quantum metrology. In this work, we investigate multiparameter quantum estimation in a hybrid exciton--optomechanical (EOM) system. The system consists of a semiconductor quantum well embedded inside a driven optomechanical microcavity, where the excitonic, optical, and mechanical modes interact coherently th...

    Theoretical quantum dynamics calculations scale deeply with system size, rendering classical calculations intractable for complex systems. While quantum computing offers a natural solution, its application to nuclear quantum dynamics remains scarce. Here, we present a quantum algorithm to study photodissociation dynamics on quantum computers, benchmarked on the NOCl molecule...

  • Impact of the Unruh effect on the estimation precision of Gaussian channel parameters

Extensive scholarly attention has been devoted to the estimation of parameters associated with Gaussian channels. However, while previous research has predominantly focused on parameter estimation within inertial frames, the noninertial scenario, part...

    Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second to optical clocks that now reach unprecedented levels of precision. A nuclear clock would shift the frequency reference from an electronic transition to the uniquely low-lying, laser-accessible isomeric transition in th...

  • Energy-Efficient Satellite Wake-Up via Bosonic Identification: The Role of Synchronization

    The information-theoretic concept of identification describes a sender-receiver architecture in which the receiver only checks whether a particular message was sent or not, thereby promising a low-energy receiver design. In low received-energy regimes, quantum receivers are a promising tool for studying the system limits. However, the known information-theoretically optimal...

  • Time Evolution of Heat Conduction in a Generalized Model of Brownian Motion

    We investigate the properties of heat conduction in a network of harmonic oscillators interacting with heat baths, described by a generalized model of Brownian motion. This model includes noise and dissipation terms in both the momentum and position equations. This generalization is motivated by the requirement of consistency with the Gorini-Kossakowski-Sudarshan-Lindblad (G...

  • Randomized simulation of quantum channels using small ancilla

    We study the problem of implementing a quantum channel using a small ancilla with classical randomization and postselection on an output failure flag. The simulation is probabilistic, but exact conditioned on success. We prove that any unital channel on a d-dimensional system can be simulated with ancilla dimension k and success probability Ω(k/(log d)). Equival...

  • Algebra of Bivariate-Bicycle Surface Codes

    We relate the properties of bivariate-bicycle-surface (BBS) codes, constructed from a pair of bivariate polynomials over a finite field, to the number and location of their common roots in the extension field. The number of roots (x,y) with finite, non-zero coordinates -- counted with algebraic multiplicity -- determines the dimension of the codes. This dimension is invari...

    Tensor networks and quantum circuits are structural objects whose meaning depends on connectivity, indices, contraction order, gate placement, measurements, and related design choices. They are often easier to reason about visually than as code, yet in Python they are frequently constructed, transformed, and checked through backend-specific objects or compact symbolic expres...
