A 21 August 2026 arXiv preprint compares classical and non-classical photon states for experiments seeking QED vacuum non-linearity, including PVLAS and all-optical four-wave-mixing configurations.

A 21 August 2026 arXiv preprint develops bounds on virtual-distillation success probability, framing the error-mitigation method as a spectral filter and deriving limits from a Slepian concentration operator.

An updated 20 August 2026 arXiv preprint presents fermionic quantum-machine-learning circuit architectures intended to balance trainability, expressivity, classical-simulation hardness, and gradient-evaluation cost.

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.

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.
