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.
2026-08-21
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.
2026-08-20
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.
2026-08-14
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.
2026-08-14
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.
2026-08-13
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.
2026-08-12
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.
2026-08-06
This arXiv preprint presents a shadow-tomography protocol with dimension-independent sample complexity and polylogarithmic dependence on the number of observables. The authors state that it answers Aaronson’s original dimension-independent sample-complexity question and gives an exponential improvement over the prior dimension-independent result, using sequential pretty-good measurements and a refined error analysis.
