Efficient Approximation of the Wigner Kernel in Phase-Space Quantum Mechanics

Mehran Attar, Bassant Selim, Jean Michel Sellier·Jun 26, 2026

The Signed Particle Formulation provides a particle-based interpretation of quantum mechanics in phase space, where quantum dynamics are represented through the creation and evolution of signed particles. A central computational challenge in this fra...

Vacuum Fluctuation-Induced State Switching in Degenerate Optical Parametric Oscillators

Yihao Huang, Seou Choi, Rom Simovitch +5 more·Jun 26, 2026

Bistable driven-dissipative systems near bifurcations can exhibit noise-activated switching between steady states. Here, we investigate how quantum vacuum fluctuations induce such switching in a biased optical parametric oscillator (OPO), a nonlinear...

Optimizing Resource Costs: A Practical Guide to Achieving Target Security in Verifiable Blind Quantum Computing

Janice van Dam, Michał van Hooft, Stephanie D. C. Wehner·Jun 26, 2026

Verifiable blind quantum computing (VBQC) enables a resource-limited client to securely delegate computations to an untrusted quantum server while maintaining privacy and detecting deviations from the prescribed computation. The noise-robust VBQC pro...

A Reproducible Pipeline for Symmetry-Respecting Excited States on Near-Term Quantum Computers: The H2O/STO-3G Case

Huajing Song·Jun 26, 2026

Variational excited-state quantum algorithms fail for reasons usually studied in isolation: barren plateaus, symmetry contamination, finite-sampling instability, and hardware cost. Using one small but complete system -- H$_2$O in the STO-3G basis (12...

Static features from mixing in short- and long-range Lindbladians: Markov property and correlations

Paul Rosa-Ruiz, Matteo Scandi, Ángela Capel +1 more·Jun 26, 2026

The classification of mixed-state phases requires criteria beyond two-point correlation functions, such as the decay of the mutual information (MI) and the conditional mutual information (CMI), with the latter encapsulated in the notion of Markov len...
