A new arXiv paper presents a hybrid workflow that keeps data assimilation and dynamical simulation classical while using a QUBO-to-Ising formulation for quantum-assisted parameter estimation.

A new arXiv hardware paper introduces edge-pass Purcell filters for superconducting-qubit readout, reporting 99.46% to 99.49% average readout fidelity with compact high-pass and low-pass implementations.

A new arXiv theory paper studies how measurement feedback and correlated records shape work statistics in a quantum information engine, including a coherence-transition interference contribution.

A new arXiv paper evaluates quantum-jump descriptions of current fluctuations in non-additive open quantum systems and identifies conditions under which imperfect jump detection recovers Landauer-Büttiker results.

This arXiv preprint proves a local uniqueness result for the Born rule in small categories with complex-weighted morphisms. Under non-negativity, bounded-degree polynomiality, global phase invariance, classical-limit path additivity, and normalization, it derives the probability assignment P(z)=|z|^2 and identifies global coherence under morphism composition as an open extension.

This arXiv preprint studies Bell correlations for a free real quantum scalar field on a noncommutative Moyal plane. The authors show that twist phases in multiparticle statistics can generate entanglement between wave-packet modes and that suitable local measurements can violate the CHSH Bell inequality, providing an operational probe of the noncommutative multiparticle sector.

A source-backed weekly read on quantum capital, company movement, research signals, policy activity, and watchlist items from the QAtlas corpus.

Aegiq reported integrating NVIDIA Ising AI models into the calibration workflow for Artemis, its first-generation photonic quantum computer deployed at the UK NQCC.

The NQCC expanded UK quantum computing infrastructure, access, and ecosystem support.
