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.
