We show that, for many-body wave functions known analytically in the occupation-number basis, systematic lower bounds to the QFI can be mapped onto expectation values over a classical probability distribution defined by the wave function amplitudes. This mapping enables efficient estimation via Markov-chain Monte Carlo sampling, with a computational cost that scales as a `slow' exponential ($e^{b L}$ with $b \lesssim 0.6$) and remains manageable for system sizes well beyond exact diagonalization. We specify this framework to Jastrow-Gutzwiller wave functions. We characterize their metrological content by identifying the observables that maximize the QFI and the corresponding scaling with $L$. Then, we analyze the QFI under three physically motivated noise channels: local dephasing, local amplitude damping, and global depolarizing. We compare polynomial and Krylov-based lower bounds across these channels, relating their behavior to the effective rank of the noisy density matrix and to the structure of the operator generating the parameter encoding. The framework extends naturally to other analytically known wave functions and to a broader class of information-theoretic quantities beyond the QFI.

quantum-computingClassical State Preparation for Variational Quantum Algorithms via Reinforcement Learning
--> Quantum Physics arXiv:2605.23138 (quant-ph) [Submitted on 22 May 2026] Title:Classical State Preparation for Variational Quantum Algorithms via Reinforcement Learning Authors:Gino Kwun, Dhanvi Bharadwaj, Gokul Subramanian Ravi View a PDF of the paper titled Classical State Preparation for Variational Quantum Algorithms via Reinforcement Learning, by Gino Kwun and 2 other authors View PDF HTML (experimental) Abstract:Variational Quantum Algorithms (VQAs) potentially offer a pathway to practical quantum advantage, but their optimization is heavily hindered by barren plateaus and numerous local minima. While classically simulable Clifford circuits can warm-start VQAs to accelerate convergence, existing heuristic-based initialization methods struggle to scale within vast combinatorial search spaces. To overcome this bottleneck, we propose CRiSP (a Clifford Reinforcement Learning agent for State Preparation), a framework that formulates discrete prefix selection as a sequential decision-making problem. CRiSP utilizes Neural-Guided Monte Carlo Tree Search, driven by a Transformer-based policy trained via self-play, to insert learned Clifford gates before fixed parameterized rotations. This enables the construction of high-quality initial states entirely through polynomial-time classical stabilizer simulation without altering the underlying circuit architecture. By integrating a curriculum learning strategy that progressively expands the search horizon, the agent efficiently scales to deep circuits. Evaluated on QAOA benchmarks of up to $22$ qubits and $1{,}370$ parameters, CRiSP outperforms state-of-the-art Clifford initialization methods by a mean of $3.17\times$ (max $45.02\times$) in average energy accuracy and $2.44\times$ (max $16.01\times$) in best-achieved energy accuracy. Assessments on VQE tasks further demonstrate the framework's robustness and generalizability. Comments: Subjects: Quantum Physics (quant-ph); Artificial Intelligence (cs.AI); Emerging Technol

quantum-computingPrediction: Quantum Computing Is 2026's Most Underrated Tech Trend
Quantum computing is often considered a speculative field, since those systems are still primarily used for niche government and research projects rather than mainstream computing applications. Quantum systems are much more powerful than classical computers, but they're also bigger, pricier, consume more power, and make more mistakes. But from 2025 to 2030, Grand View Research expects the global quantum computing market to expand at a 20.5% CAGR as smaller, more scalable, and more accurate systems hit the market. They could also be deployed for a broader range of purposes, including processing AI tasks, streamlining supply chains, developing new drugs, and strengthening cybersecurity services. Image source: Getty Images. That's why it wasn't surprising when the U.S. government recently ramped up its investments in the quantum computing market, sending many of those stocks soaring. On May 21, the U.S. Department of Commerce said it had signed nine letters of intent to provide $2.01 billion in federal incentives under the CHIPS and Science Act to support a portfolio of quantum computing companies. Let's see which companies will profit from those fresh government investments, and why they imply the growth of the quantum computing market is still an underrated tech trend right now. Which nine companies will benefit from those investments? The Department of Commerce has earmarked $1 billion for IBM (IBM +0.34%) and $375 million for GlobalFoundries (GS +0.87%) to build new domestic quantum computing foundries.

quantum-computingQuantum Doeblin Coefficients: Interpretations and Applications
AbstractIn classical information theory, the Doeblin coefficient of a classical channel provides an efficiently computable upper bound on the total-variation contraction coefficient of the channel, leading to what is known as a strong data-processing inequality. Here, we investigate quantum Doeblin coefficients as a generalization of the classical concept. In particular, we define various new quantum Doeblin coefficients, one of which has several desirable properties, including concatenation and multiplicativity, in addition to being efficiently computable. We also develop various interpretations of two of the quantum Doeblin coefficients, including representations as minimal singlet fractions, exclusion values, reverse max-mutual and oveloH informations, reverse robustnesses, and hypothesis testing reverse mutual and oveloH informations. Our interpretations of quantum Doeblin coefficients as either entanglement-assisted or unassisted exclusion values are particularly appealing, indicating that they are proportional to the best possible error probabilities one could achieve in state-exclusion tasks by making use of the channel. We also outline various applications of quantum Doeblin coefficients, ranging from limitations on quantum machine learning algorithms that use parameterized quantum circuits (noise-induced barren plateaus), on error mitigation protocols, on the sample complexity of noisy quantum hypothesis testing, on the fairness of noisy quantum models, and on mixing, indistinguishability, and decoupling times of time-varying channels. All of these applications make use of the fact that quantum Doeblin coefficients appear in upper bounds on various trace-distance contraction coefficients of a quantum channel. Furthermore, in all of these applications, our analysis using quantum Doeblin coefficients provides improvements of various kinds over contributions from prior literature, both in terms of generality and being efficiently computable.► BibTeX data@artic

Flatiron Institute Tensor Network Algorithm Overturns Historical D-Wave Quantum Supremacy Claim Physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation’s Flatiron Institute, in collaboration with Boston University, have developed a classical algorithm that successfully simulates complex three-dimensional quantum dynamics previously claimed to be impossible without a quantum computer. Published in Science, the study refutes a high-profile “beyond-classical” computation milestone reported in March 2025 by researchers utilizing D-Wave Systems’ 5,000-qubit Advantage2 superconducting quantum annealing processor. By repurposing and optimizing decades-old data compression and mathematical routing techniques, the CCQ team proved that classical workstations—and in some configurations, standard commercial laptops—can achieve state-of-the-art accuracy when calculating highly entangled quantum state progressions. Technical Architecture & Specifications / Operational Implementation The computational breakthrough targets the simulation of continuous-time quantum dynamics within the transverse-field Ising model (TFIM) across multi-dimensional square, cubic, and diamond disordered spin-glass lattices. The 2025 D-Wave demonstration relied on the premise that as hundreds of interacting qubits undergo a rapid quench through a quantum phase transition, the system’s wave function generates area-law entanglement that causes classical matrix-product-state approaches to scale exponentially in memory and runtime. To bypass this exponential memory wall without directly storing the massive wave function, the CCQ team constructed a lattice-specific, three-dimensional tensor network architecture utilizing ITensor, an in-house high-performance software library. The mathematical implementation processes the state evolution via a two-stage pipeline: Time Evolution Tracking: The algorithm adapts belief propagation (BP)—a localized message-passing routine origin

Diraq has secured a Letter of Intent for 38 million in proposed funding from the U.S. Department of Commerce through the CHIPS Research and Development Office, a commitment designed to scale domestic production of silicon quantum computing processors. The company’s approach, leveraging silicon spin technology, is potentially a more economical and scalable path toward utility-scale quantum computing than other qubit technologies currently in development. “The Department of Commerce’s incentives strengthen U.S. quantum leadership and technological resilience,” said Bill Frauenhofer, Executive Director of Semiconductor Investment and Innovation. This investment builds upon 25 years of U.S. government support, through the U.S. Army Research Office and DARPA, that underpins Diraq’s technology, potentially establishing a fully American quantum supply chain for cryostats, chips, and packaging. 38M CHIPS Act Funding to Scale Silicon Quantum Processors A proposed 38 million investment from the U.S. Department of Commerce signals a move toward silicon-based quantum computing, specifically targeting the scaling of processors developed by Diraq. Diraq’s approach centers on utilizing existing CMOS manufacturing processes, a strategy designed to circumvent the substantial infrastructure hurdles facing other quantum modalities and potentially deliver millions of qubits on a single chip. This financial commitment is not a sudden endorsement, but rather a continuation of decades-long government support; Andrew Dzurak, Diraq Founder and CEO, explained that “The U.S. Government has played an important role for over 25 years in funding silicon quantum research through entities such as the U.S. Army Research Office and more recently DARPA.” Diraq is targeting a price point of less than 1 per physical qubit, a critical threshold for utility-scale quantum computing, and designing systems compatible with standard data center infrastructure.

quantum-computingRobots Learn Navigation Using Quantum Processing and Achieve Stable Trajectories
Mohamed Khair Altrabulsi and colleagues at NYUAD Research Institute, in collaboration with New York University, present Q-SpiRL, a quantum spiking reinforcement learning framework for obstacle-aware robot navigation in dynamic environments. Their research compares five agent families, focusing on a quantum-enhanced spiking neural network (QSNN) integrating spike-based temporal processing with quantum feature transformation. Experiments in grid-world environments, ranging from 20×20 to 40×40, show QSNN achieves a success rate of up to 99% while maintaining efficient and smooth trajectories, and key validation confirms the feasibility of deploying this hybrid policy on actual IBM quantum hardware. Quantum spiking neural networks achieve near-perfect robotic navigation in complex environments A 99% success rate in complex grid-world environments was attained by a new quantum-enhanced spiking neural network, exceeding previous capabilities in robot navigation. High reliability and efficient path planning in active environments previously proved difficult for robotic systems, with conventional methods struggling to scale effectively with increasing complexity. The Q-SpiRL framework, utilising a quantum spiking neural network (QSNN), combines the benefits of spike-based temporal processing, mimicking the brain’s efficient signalling, with variational quantum feature transformation to refine data interpretation. Traditional reinforcement learning algorithms often require extensive training and struggle with the ‘curse of dimensionality’ as the environment’s complexity increases, leading to slow learning times and suboptimal policies. Q-SpiRL addresses these limitations by leveraging the principles of both spiking neural networks and quantum computation. The Q-SpiRL framework outperformed tabular Q-learning, classical multilayer perceptrons, classical spiking neural networks, and quantum-enhanced multilayer perceptrons in terms of task completion, trajectory efficiency, and

quantum-computingQuantum Entanglement’s Paradox Explained by Standard Theory Alone
Gregory D. Scholes, at Princeton University, and colleagues have revealed how a single wavefunction encapsulates a range of potential measurement results. The approach explains both state vector collapse and the seemingly paradoxical nonlocal correlations observed between separated quantum subsystems. Quantum correlations, even those violating Bell’s inequality, arise naturally from classical measurements, offering a thorough explanation within the existing framework of quantum theory without requiring additional assumptions or nonlinearities. Mapping entangled states via Cartesian product decomposition reveals subsystem properties Dr. Eleanor Rieffel and colleagues at Quantum AI employed a technique focused on dissecting the overall description of an entangled state, a complete description of a quantum system, into the individual components representing its separated subsystems. Mathematically mapping the combined system’s state vector onto a Cartesian product of vector spaces effectively created separate ‘blueprints’ for each subsystem. This decomposition isn’t merely a mathematical convenience; it reflects the physical separability of the subsystems even while acknowledging their quantum connection. The Cartesian product allows for the representation of the combined system’s state as a tensor product of individual subsystem states, facilitating analysis of each component’s contribution to the overall entanglement. This process accounted for contextual phase factors, subtle elements within the initial state that encode how measurements on one subsystem influence the others, and these factors are inherent to the system’s description but not immediately obvious. These phase factors are crucial because they determine the interference patterns that give rise to quantum correlations and are directly linked to the system’s evolution over time. Ignoring them would lead to an incomplete and inaccurate representation of the entangled state. The technique avoids assumptions

DQCs use teleportation to relocate qubits and execute CNOTs between qubits on different chips. However, non-local CNOTs are 4.3-7.7$\times$ slower and 4$\times$ more error-prone than local CNOTs within a chip, which degrades program fidelities. Existing compilers group CNOTs with overlapping qubits into blocks and collectively optimize teleportations for each block. However, block-level scheduling has two key drawbacks. First, it lacks lookahead ability across blocks because it selects the optimal schedule for one block before proceeding to the next. As a result, it cannot assess the impact of a teleportation on future blocks. Our studies show that naively expanding the lookahead window to include subsequent blocks does not address this issue. Second, existing approaches do not schedule future block operations or the teleportations they require until preceding blocks are fully scheduled, introducing delay and latency overheads. We propose ATHENA, a DQC compiler that addresses these limitations using two key insights: Utility-driven Lookahead with Multi-Candidate Block Scheduling (UMS) and EPR-Capacity-Aware Early Scheduling (EES). UMS schedules a block by considering only useful future blocks in its lookahead window. A future block has utility if it shares overlapping qubits with the current block being scheduled. UMS also maintains multiple

quantum-computingDid Amazon Just Deliver a Sweeping Blow to IonQ?
Amazon's (AMZN +1.29%) quiet engagement with IonQ (IONQ +10.21%) reflects the careful ways large companies may choose to explore new business opportunities. Rather than making a long-term commitment, the tech giant made a small investment in the quantum computing specialist, representing a tactical move within a broader strategy related to its cloud-based quantum computing services. Image source: The Motley Fool. Taking a look at Amazon's investment in IonQ According to 13F filings, Amazon took an initial stake in IonQ during the second quarter of 2025, acquiring 854,207 shares. Technology giants like Amazon don't typically buy shares in specialized companies without clear business alignment. I think the investment in IonQ allowed the company to signal potential interest for a collaboration with Amazon Web Services (AWS) while also gaining indirect exposure to advancements in trapped-ion quantum systems. Investing in IonQ could have been a way to strengthen ties in AWS' emerging quantum ecosystem without requiring Amazon to raise its already aggressive capital expenditure roadmap. At the end of the day, the scale of its IonQ investment remained modest relative to Amazon's liquidity resources, suggesting it served more as a bridge and a hedge for its internal developments rather than a core pillar of the company's quantum AI roadmap.

quantum-computingInfleqtion Releases Neutral-Atom Core Architectural Milestones Across Hardware, Software, and Theory
Infleqtion has unveiled a series of technical milestones that advance its full-stack neutral-atom quantum computing architecture toward utility-scale, fault-tolerant operations. The coordinated announcements span software resource estimation tools, record physical gate fidelities, gate-design optimization theory, and novel atomic transport mechanics. Tightly coupling these distinct structural layers is designed to accelerate surface-code quantum error correction (QEC) timelines, support efficient magic-state distillation, and allow rapid design iterations. The commercial scale-up is backed by Infleqtion’s recent transition to a publicly traded corporation via a business combination with Churchill Capital Corp X. Open-Source Resource Estimation Middleware In software, Infleqtion and the University of Chicago have open-sourced resource-superstaq, an architecture-level resource estimation package integrated into the company’s commercial Superstaq ecosystem. The compilation-driven software translates arbitrary algorithmic circuits into logical primitive operations with mapped physical hardware constraints, enabling users to extrapolate logical qubit counts, routing delays, and circuit runtimes against public hardware roadmaps. The compiler allows configurable hardware assumptions to evaluate how design choices—such as multi-species arrays, dedicated measurement zones, and atom-shuttling trajectories—impact application-level performance. Early testing on fault-tolerant simulation benchmarks indicates that while magic-state production remains the dominant overhead bottleneck, optimized, movement-aware compilers can mitigate routing delays during logical state cultivation.

By analyzing sensor data from industrial equipment, such approaches aim to detect irregularities at an early stage, helping to reduce downtime, improve quality control, and increase overall efficiency. The study focused on practical scenarios such as identifying pneumatic leaks and detecting faults in rotating machinery, illustrating how quantum-enhanced models could complement existing data-driven solutions in industry. Building on this application perspective, the team conducted a systematic evaluation of Quantum Neural Networks (QNNs), a class of machine learning models designed for near-term quantum hardware. The results show that QNNs can achieve competitive performance, including 87.77 percent accuracy in pneumatic leak detection and strong ROC-AUC performance on NASA bearing fault datasets. The study further analyzes key design choices such as data encoding strategies, highlighting binary and exponential encodings as effective trade-offs between model expressivity and trainability. The full technical details are available in the corresponding arXiv publication. »Quantum Neural Networks (QNNs), holds promise for integrating quantum principles into machine learning.
