Operator brief

  1. AMD EPYC Venice enters TSMC 2nm production

    [rising] -- AMD confirmed a production ramp (not just tape-out) of its next-generation Venice server CPU on TSMC 2nm. This is the leading proof point that the node yields at volume for complex logic die, and it gates GPU and AI accelerator migration planning to the same node.

  2. ERCOT hits 91.1 GW hourly peak; US battery fleet at 51.9 GW

    [blocker] -- Texas grid set a new all-time hourly peak on July 22 just as US utility-scale battery storage crossed 51.9 GW nationally (70% average annual growth over three years). The convergence of AI data center load and seasonal peaks is compressing operational margin in the region with the highest concentration of announced AI campus capacity.

  3. SK Group signs $500B+ LOI with NVIDIA covering AI factories and HBM supply

    [rising] -- SK Group signed letters of intent with NVIDIA for a package described as exceeding $500 billion, spanning AI factory construction, AI memory supply, and telecom AI cloud deployment. These are LOIs, not executed contracts. If converted to execution, this represents the largest single-entity AI infrastructure commitment on record.

Quantum

  • P1 Morgan Stanley U.S. Innovation Initiative (Quantum + Strategic Technologies)

    A major investment bank formally names quantum as a strategic technology within a dedicated U.S. initiative.

    The read: Institutional capital earmarking quantum in a named vehicle is a different signal than conference sponsorship. It implies portfolio-level thesis formation rather than exploratory interest.

  • P2 Qunnect and Monarch Quantum: Deployable Quantum Networking Hardware Partnership

    Two quantum networking companies partnering on field-grade hardware -- the critical gap between demonstration and infrastructure.

    The read: The word "deployable" is the operative signal. Field-grade reliability requirements are an order of magnitude more demanding than lab demonstrations; partnerships targeting them indicate a maturation step.

  • P2 Infleqtion Selected by Eaton for Power Grid Resilience (Quantum-Grid Cross-Sector)

    Eaton, a grid equipment manufacturer, is exploring neutral-atom quantum computing for power grid resilience with Infleqtion.

    The read: The grid resilience framing suggests optimization and scheduling workloads, not cryptography. Industrial verticals mapping concrete near-term workflows is a sector maturity indicator.

Chips

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

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

    The read: Production ramp (not tape-out) is the gating confirmation that TSMC 2nm yields at volume for complex logic. This is the reference proof point for GPU and AI accelerator migration timelines to the same node.

  • P1 HBM as 3D Assembly Yield Testbed

    High-bandwidth memory has become the proving ground for 3D stack yield, test, and DFT methodology across the industry.

    The read: As AI accelerators require more HBM stacks per die, yield methodology proven on HBM will gate AI compute cost structure. Advances in HBM test translate directly to accelerator economics.

  • P2 AI Chiplet Architectures Redefining Test Insertions

    Heterogeneous chiplet integration redistributes where quality assurance must occur, not just how much of it there is.

    The read: As AI accelerators move toward chiplet designs, test insertion becomes a design-time decision. Misalignment between chiplet interface specs and test coverage produces systematic yield loss at scale.

  • P2 AMD AAI 2026: Full-Stack Compute for Agentic AI Era

    AMD presented its full-stack compute strategy for agentic AI at its 2026 Advancing AI event.

    The read: AMD framing a distinct "agentic AI" compute segment signals that inference workload differentiation is now driving product-line strategy, with NVIDIA as the implicit benchmark.

Power

  • P1 ERCOT Hourly Peak Record: 91.1 GW (July 22, 2026)

    Texas grid set a new all-time hourly peak, compressing operational margin in the US region with the highest concentration of announced AI campus capacity.

    The read: ERCOT now operates with less summer headroom than any prior year. AI data center load is additive to seasonal peaks, not a substitute. Each successive record tightens the buffer for unforced outages.

  • P1 US Battery Storage: ~51.9 GW at Mid-2026 (70% Avg Annual Growth, 3yr)

    Utility-scale battery storage added 8.3 GW in H1 2026, crossing 51.9 GW -- the third consecutive year of roughly 70% average annual growth.

    The read: Storage at this scale is now material for intraday dispatch on large AI campus loads. Grid operators can increasingly use storage to smooth the late-afternoon demand peak that AI data centers intensify.

  • P2 Champlain Hudson Power Express: Commercial Operation (Quebec-NYC)

    A new high-voltage DC line from Quebec to New York City reached commercial operation; first-day import was 52 GWh.

    The read: New cross-border transmission into New York City adds grid capacity headroom for AI-dense metro builds in the Northeast where transmission, not generation, is the binding constraint.

  • P2 GE Vernova Expanding Pennsylvania Grid Equipment Manufacturing

    GE Vernova is expanding its Charleroi, PA facility producing high-voltage circuit breakers, switchgear, and instrument transformers.

    The read: Domestic grid equipment production expansion signals GE Vernova is front-running delivery lead-time pressure on substation hardware, a known bottleneck for new AI campus interconnect timelines.

AI Compute

  • P1 SK Group + NVIDIA: $500B+ AI Factory and Memory Package (LOI)

    SK Group and NVIDIA signed letters of intent covering AI factory construction and AI memory supply at a scale described as exceeding $500 billion.

    The read: LOIs are not contracts. The $500B+ figure represents the stated ambition, not committed capital. If executed, it would represent a structural shift in Korean chaebol capital deployment toward AI infrastructure at a scale that would affect global HBM supply allocation.

  • P1 NVIDIA + SK hynix: Multiyear AI Factory Memory Technology Partnership

    NVIDIA and SK hynix formalized a multiyear technology partnership for next-generation AI factory memory, distinct from the broader SK Group LOI.

    The read: A direct technology partnership (vs. a standard supply agreement) suggests NVIDIA is co-designing memory architecture with the supplier. This could compress HBM specification cycles by removing the typical arm's-length spec handoff.

  • P2 NAVER Sovereign AI Infrastructure: 55 MW Start, Gigawatt-Scale Plan (NVIDIA DSX)

    NAVER will expand sovereign AI cloud starting at 55 MW, with a stated plan for gigawatt-scale deployment using the NVIDIA DSX platform.

    The read: 55 MW is the announced anchor, not the ceiling. The DSX platform adoption means NAVER is taking the full-stack factory design, not just hardware -- a higher lock-in signal.

  • P2 NVIDIA Industrial AI Cloud: Germany, 10,000 GPUs

    NVIDIA is building an industrial AI cloud for European manufacturers in Germany, anchored at 10,000 GPUs including DGX B200 systems.

    The read: A concrete GPU count in a press release is a buildout commitment, not a roadmap placeholder. DGX B200 inclusion confirms Blackwell architecture deployment at industrial-scale.

  • From Barren Plateaus to SPSA Optimization in Variational Quantum Eigensolvers

    The barren plateau (BP) phenomenon poses a fundamental challenge to the trainability of variational quantum eigensolvers (VQEs) by causing exponentially vanishing gradients as the system size increases. While extensive studies have investigated the geometric origins of BP, its impact on the optimization dynamics and complexity of practical algorithms under finite-shot measur...

  • Aicir: A Full-Stack Quantum Circuit Simulator with AscendNPU Support

    Quantum computing is a promising way to study problems that are difficult for classical methods, but current quantum hardware still faces limits in scale, noise, and fidelity. Running quantum algorithms on physical machines can also be costly. Quantum circuit simulators therefore remain important because they let researchers design and test algorithms on classical computers...

  • Memory-, Circuit-, and Ansatz-Efficient VQLS for CFD on Hybrid Quantum-HPC Systems

    Fluid dynamics workloads are dominated by repeated solves of large, structured linear systems, motivating the search for quantum acceleration. The Variational Quantum Linear Solver (VQLS) is a leading near-term candidate, but practical deployment on hybrid quantum--high--performance computing (HPC) systems faces three persistent challenges: (i) the linear-combination-of-unit...

  • QSVM-RQNN: Low-Qubit Recurrent Quantum Similarity Learning for Condition Monitoring and Fault Classification

    In the Noisy Intermediate-Scale Quantum (NISQ) era, limited qubit availability and hardware noise constrain the practical deployment of quantum machine learning (QML). Existing quantum neural network (QNN) and quantum convolutional neural network (QCNN) architectures often require increasing quantum resources as the input dimension grows, limiting scalability on near-term de...

  • Autoregressive Projective Quantum Monte Carlo: From a Hermitian to a Non-Hermitian Perspective

    Accurately determining the ground-state properties of quantum many-body systems remains a central challenge. In this work, we introduce an autoregressive projective quantum Monte Carlo (PQMC) framework that leverages recurrent neural networks (RNNs) to guide the stochastic dynamics. By incorporating autoregressive sampling into PQMC, we demonstrate substantial improvements i...

  • A non-Markovian approach to spin-phonon coherence and the breakdown of the Markovian approximation

    Qubit coherence is an essential figure of merit for quantum information processing applications such as quantum computing, or quantum repeaters. Understanding the coherence properties of the underlying physical qubits that facilitate such applications is therefore are often limited by coupling to lattice phonons, which in turn constrains operation temperature. Here we study...

  • A Quantum Coherence Microscope in the Hubbard Regime

    Quantum coherence underlies collective quantum phenomena and emerging quantum technologies. Quantum gas microscopes have transformed quantum simulation by providing projective snapshots of many-body states with single-atom resolution, but spatially resolved measurements of off-diagonal correlations have remained elusive. Here, using the Talbot effect, we introduce a quantum...

  • The quadratic growth of Krylov spread complexity in the BTZ black hole

    The boundary quantity that captures the growth of black-hole interiors quantified by holographic complexity remains unknown beyond 2d dilaton gravity. We provide a critical analysis of a partition-function construction of Krylov spread complexity for thermofield-double states that provides a dimension-independent boundary reconstruction from semiclassical holographic partiti...

  • Decoupling 2D translation-invariant topological CSS codes

    Two-dimensional translation-invariant topological CSS codes on qubits are known to be locally equivalent, after coarse-graining, to stacks of toric codes. However, existing constructions generally break more translation symmetry than is required to remove anyon-permuting translations, leaving open whether any further obstruction exists. We prove that no such obstruction occu...

  • Learning Clifford-structured quantum unitaries and Hamiltonians

    Learning algorithms for structured quantum unitaries and Hamiltonians have primarily considered classes of processes that are local or sparse in the Pauli basis. We turn our attention to learning n-qubit quantum unitaries U and Hamiltonians H, given query access to U or the unitary evolution of H, that may be dense in the Pauli basis but still admit concise Cliffor...

  • Tensor network methods for non-perturbative dynamics of open quantum systems

    The description of open quantum system dynamics beyond the perturbative treatment (usually associated with Markovian master equations) is a computationally challenging task due to the unfavorable exponential scaling of memory kernels. Developed over recent decades in the context of quantum information and condensed matter, tensor networks provide both a new formalism and a t...

  • An upper bound for the purity of absolutely positive partial transpose states

    A quantum state is called absolutely separable (resp. absolutely positive partial transpose (APPT)) if it remains separable (resp. positive partial transpose (PPT)) under any global unitary transformation. It is known that the set of all absolutely separable states is a subset of the set of all APPT states. Moreover, these two sets are identical for qubit-qudit systems. In t...

  • Quantum Information Flow under String-Diagram Rewriting

    We revisit the notion of ``quantum information flow'' introduced in Bob Coecke's early work and seek to give it an explicit string-diagrammatic formalization. Given a semantics preserving string-diagram rewriting sequence, we first distinguish apparent through-paths, which depend on the current graphical presentation, from genuine through paths, which can be compatibly inher...

  • Autonomous Lindblad Realizability of Nonunitary Linear Dynamics with a Carleman Lattice Boltzmann Application

    Carleman lifting converts nonlinear polynomial dynamics into finite linear systems, but the resulting truncations are generally nonunitary and need not correspond to physical quantum evolution. We prove that a finite linear endpoint admits an autonomous Gorini--Kossakowski--Sudarshan--Lindblad (GKSL) realization on vacuum coherences if and only if it is invertible and power...

  • Security of quantum key distribution with passive basis choice and detection-efficiency mismatch for a realistic satellite setup

    Detection-efficiency mismatch is a common problem in realistic quantum key distribution (QKD) systems. The existing security proofs for the case of the passive basis choice provide a nonzero secret key rate only for a small detection-efficiency mismatch. Unfortunately, in realistic setups, the detection-efficiency mismatch can be significant. Here we present a more precise e...

  • State Diagnostics of Complexity in Open Quantum Systems

    We study the emergence of complexity in finite-size quantum systems as their dynamics transition from closed and coherent evolution to interacting and effectively open behavior. Using a state-based geometric framework, we represent mixed quantum states as probability measures on complex projective Hilbert space. This representation allows us to track how interactions reshape...

  • Spread of Entanglement in Generalized Kicked Ising Chain

    We investigate the dynamics of entanglement in a generalized version of the kicked Ising chain, extending the model from the standard qubit case (local dimension q=2) to higher local dimensions (q > 2). We identify the existence of ''dual-unitary'' points where the model's space-time duality allows for exact analytical solutions. Our analysis reveals that while a few uni...

  • Collective-dissipation-induced dark and metastable-like states for enhanced quantum battery performance

    We investigate the role of symmetry-protected dark states and metastable-like frozen states in the autonomous charging dynamics of open quantum batteries described by a transverse-field Ising model. By comparing local and collective dissipation over a range of system sizes, temperatures, and magnetic phases, we demonstrate that collective dissipation generates symmetry-prote...

  • An Efficient Explicit Implementation of a Quantum Algorithm with Quantum Advantage for Nonlinear Scalar Conservation Laws

    Quantum algorithms for nonlinear partial differential equations remain challenging because nonlinear dynamics are not directly amenable to unitary quantum simulation. Building on the level-set formulation, we construct a quantum algorithm and provide an explicit gate-level implementation for solving scalar conservation laws. The nonlinear equation is first lifted to a linear...

  • Phase-error estimation for quantum key distribution with leaky receivers

    Practical quantum key distribution (QKD) receivers may leak information about their measurement outcomes and settings to the channel (e.g., through detector backflashes or back-reflected Trojan-horse light) that could compromise the protocol's security. Here we present a simple finite-key security proof based on phase-error estimation for prepare-and-measure QKD in the prese...

  • Characterising the set of deterministic quantum correlations in prepare-and-measure scenarios

    Correlations that do not admit a deterministic explanation are a central feature of quantum theory and a key resource for quantum information processing. Identifying and certifying such correlations, however, remains a fundamental challenge. In this work, we advance on this problem by considering deterministic correlations in the prepare-and-measure scenario consistent with...

  • A Domain-Specific Language for Formulating Hybrid Quantum-Classical Meta-Solver Strategies

    A key challenge when designing hybrid quantum-classical workflows is the identification of quantum candidates, that is, determining for which specific problems quantum advantages could potentially be achieved. When choosing between several candidates, it is crucial to consider the characteristics specific to the problem, as these can fundamentally determine how successful qu...

  • Conditions for implementing projective measurements through continuous monitoring

    Projective measurements are foundational for quantum physics in general and quantum information tasks in particular. However, their direct implementation is often not warranted. Here, we investigate under what conditions continuous monitoring that manifests in quantum jump trajectories realises projective measurements over time. Considering finite-dimensional quantum systems...

  • Time Dilation and center of Mass Normalization in the Page-Wootters Formalism

    In this work, we study the emergence of relativistic effects in a composite quantum clock within the Page-Wootters relational formulation of quantum mechanics. We consider a system with internal and center-of-mass degrees of freedom and analyze the conditioned evolution of the center-of-mass relative to the internal system treated as an internal clock. We show that the inter...

  • Quantum Uncomputation of Clean and Dirty Ancilla Qubits

    Automatic uncomputation aims to provide programming-language-level support to facilitate the correct and safe use of ancilla qubits in quantum computing, but efforts have only been made for clean ancillas, leaving dirty ancillas unexplored. We present a unified formalization of the uncomputation of both clean and dirty ancillas. For the first time, we prove that checking the...

  • Conditional non-Hermitian acceleration of multiphoton atomic transitions

    Continuous monitoring can convert a dissipative channel into a resource for accelerating otherwise slow multiphoton transitions. We consider a three-level atom in a Λ configuration and condition the evolution on the absence of photon emission through an auxiliary monitored decay channel. The resulting no-jump dynamics is governed by a non-Hermitian Rabi-type Hamiltonian. U...

  • Quantum Coordination and Nonlocal Games: Theory and Applications

    Coordination is a fundamental primitive in communication and information theory, in which distributed systems must collectively generate correlated behavior rather than merely exchange messages. In quantum networks, the nature of entanglement, quantum measurements, and nonclassical correlations introduces coordination possibilities unavailable classically. This article revie...

    Compound beams composed of simple experimental blocks (detected in simultaneous detection windows) that form specific quantum-correlated structures are suggested for simulating the properties of different quantum operations used for creating highly nonclassical and entangled multi-mode states needed in quantum communication, metrology, and information protocols. Qualitative...

    We study algorithms for approximating the multimarginal optimal transport (MOT) distance, a generalization of the classic optimal transport distance, between m discrete probability distributions each supported on at most n points. We give a classical algorithm that computes a coupling between these marginals whose expected transportation cost is within an additive vare...

  • Genuinely Unextendible Product Bases from Maximum Distance Separable Codes

    The existence of genuinely unextendible product bases (GUPBs), incomplete orthogonal sets of fully product states whose orthogonal complements contain no product vector across any bipartition, has remained an open problem. Here we construct GUPBs for any number N≥3 of parties using classical maximum distance separable (MDS) codes. The MDS property imposes a rigidity on...

  • Quantum sensing composite excitations in an anisotropic ferromagnet via a qubit

    Ordered magnets harbor intrinsically squeezed ground states and magnonic excitations characterized by entanglement between spins and nonclassical magnon number composition. A pathway to detecting the superpositions of noneigenmode magnon number states underlying these nonclassical magnetic ground states has recently been demonstrated by utilizing a qubit coupled to the magno...

  • Probing Non-equilibrium baths: Frequency-Resolved Thermometry and Quantum Heat Current Turnover

    Quantum heat transport for non-equilibrium steady state (NESS) exhibits a characteristic turnover effect, where the heat current reaches a maximum and subsequently declines as system-bath coupling increases. Although numerically exact methods can simulate this non-monotonic behavior, they offer limited information on the thermal state of the heat baths. Here, we introduce a...

  • An accelerator-based source of high-intensity quantum-entangled annihilation gamma photons

    We present the concept and development of a novel accelerator-based source of high-intensity quantum-entangled 511 keV gamma-ray pairs produced through positron-electron annihilation. The source leverages the unique capabilities of the proposed Jefferson Lab positron facility to generate polarized, high-current positron beams with a well-defined time structure. These beams e...

  • Birefringent Biomineral Microcarriers Stabilise Multimodal Nanodiamond Quantum Sensing in Liquids

    Mobile nanodiamond quantum sensors in liquids are limited by Brownian rotation, variable photon collection, and perturbations introduced by optical trapping. Here, we assemble 40-nm nitrogen-vacancy nanodiamonds at the surface of porous, birefringent vaterite microspherulites. This carbonate biomineral provides a polarization-addressable body frame, anisotropic emission redi...

    In this paper we introduce the new version of QTris, a board game designed to teach and learn Quantum Mechanics within the framework of Quantum Information and Computation. The key idea behind the game is that every game sequence simulates a process on a system of qubits. Thus, QTris can be effectively integrated as a pedagogical tool to teach Quantum Mechanics at high-schoo...

  • Geometrical approach and topological electron density in the p_x + ip_y superconductor

    We present an analysis on the geometrical and physical nature of the p_x + ip_y superconductor on the square lattice, with an emphasis on the topological phase transition at half-filling. We develop a local topological marker from specific Dirac points within the Brillouin zone, which is introduced via the addition of two one-dimensional (1D) Z (Z_2)...

  • High-fidelity controlled-phase gates for distinguishable quantum walkers via extended interactions

    We investigate the implementation of controlled-phase (CP) gates with quantum walks in a dual-rail encoding through the use of interacting particles. While previous proposals have focused on indistinguishable particles (bosons or fermions) to achieve unitary fidelity for plane-wave scattering, practical implementations require finite-size wavepackets and routing through sing...

  • Quantum uncertainty in a macroscopic domain

    We develop a classical model-theoretic representation of partial Boolean algebras and use it to formulate quantum-like uncertainty without abandoning classical propositional logic. Given a surjection from the initial formulæ of a propositional language onto a partial Boolean algebra (V,Π), we construct a consistent theory T_g whose core---the ordered se...
