Decoherence and nonclassicality of photon-added/subtracted multi-mode Gaussian states

2022 · arXiv (Cornell University)

Photon addition and subtraction render Gaussian states non-Gaussian. We provide a quantitative analysis of the change in nonclassicality produced by these processes by analyzing the Wigner negativity and quadrature coherence scale (QCS) of the resulting …

Entanglement, loss, and quantumness: When balanced beam splitters are best

2024 · arXiv (Cornell University)

Quantum optics routinely uses beam splitters to generate entanglement, including in pioneering experiments conducted by Hanbury-Brown and Twiss and Hong, Ou, and Mandel. The quantum interference at beam splitters lies at the heart of what …
