Equivalence of Correlated Catalytic and Marginal Asymptotic Transformations in Quantum Resource Theories
We prove that correlated-catalytic state conversion is possible if and only if the marginal asymptotic conversion rate is at least one.Thermodynamics-Informed Learning Captures Hierarchical Hydrogen-Bond Networks in Deep Eutectic Solvents
Deep eutectic solvents (DESs) offer a tunable platform for lignocellulose refining, but their solvation behavior depends on multicomponent hydrogen-bond networks rather than individual constituent…Compatibility of Pauli Observables
Given an arbitrary finite family of Pauli observables, how sharply can they be approximated by a single measurement?Discovering correlated error mechanisms: data-driven augmentation of detector error models improving decoding
Accurate decoder priors are essential for high-performance quantum error correction.Cryogenic suppression of correlated loss in Rydberg atom arrays
Blackbody radiation (BBR) poses a central challenge for quantum science with Rydberg atoms.A Counterexample to the Weak Gibbs and Regularity Conjectures
We provide a counterexample to the weak Gibbs and regularity conjectures.Noise-regularized training of quantum circuit Born machines under a finite shot budget
Quantum circuit Born machines (QCBMs) can learn distributions that are hard to sample from classically, but their value depends on generalizing from finite training data.Precision Limits and Non-Gaussian Advantage in Optical Phase Estimation under Preparation Constraints
In optical quantum metrology, the scaling of the quantum Fisher information (QFI) with the mean photon number is a standard benchmark for relating precision to probe resources.Efficient quantum ultraspherical transform and a well-conditioned quantum spectral method
Solving differential equations is a promising application of quantum computing.Flux Crosstalk Calibration from Zero Knowledge to High Precision in Fully Tunable Superconducting Circuits
Precise and independent flux control is essential for scalable superconducting processors built from frequency-tunable qubits and couplers, but flux crosstalk undermines it.Experimental activation of hidden metrological steerability in quantum channels via stochastic filtering
Quantum steering-assisted metrology allows a trusted party (Bob) to improve local phase estimation by exploiting classical information communicated by an untrusted party (Alice).QASPA-MaxCut on Unweighted Graphs: Edge Encoding and QAOA Restarts
Max-Cut is a common testbed for near-term quantum optimization because it has a simple Ising Hamiltonian, established classical baselines, and a parameterized quantum circuit whose performance…Phase-Locked Quantum Battery Charging via Dissipative Mode Selection
We investigate how dynamical instability and reservoir engineering can be harnessed to enhance the quality of quantum-battery charging in a bosonic two-mode system.Solving a non-abelian hidden subgroup problem on a trapped-ion quantum computer: the power of the measurement basis
The hidden subgroup problem (HSP) unifies many of the best-known quantum speed-ups.A Quantum Lower Bound for Triangle Finding
Triangle finding is a fundamental problem in graph theory that has played a central role in the development of quantum algorithmic techniques.Near-Quantum-Limited Readout for the Princeton Axion Search using a sub-GHz Kinetic Inductance Traveling Wave Parametric Amplifier
Parametric amplifiers are a workhorse for near-quantum-limited measurements above 1 GHz.Non-compact Kogut-Susskind gauge theories: 1D lattice models with exact ${\rm SL}(2,\mathbb{R})$ gauge invariance
The Kogut-Susskind (KS) formulation of gauge theories constructs quantum many-body Hamiltonians with gauge invariance under a compact Lie group exactly implemented on a spatial lattice.Entanglement Entropy in Non Relativistic Collisions
We study numerically the build-up of entanglement entropy between two colliding, non relativistic particles, that are driven by the plain Schrödinger equation containing local, finite range…Resource-efficient formulations of the Knapsack problem for quantum computing
Quantum computing has emerged as a new tool for solving combinatorial optimization problems.Finite-temperature transition-window weights on a fault-tolerant quantum computer: duplex filtering on a thermal purification
The excite-filter-readout framework of Kharazi et al. computes zero-temperature response windows on a fault-tolerant quantum computer from a pure ground state.
