  1. Thermal-difference states of light: true states of heralded photons

    2019 · EPJ Web of Conferences

    We introduce a three-parameter family of single-mode optical states whose density operator is a weighted difference of two thermal states, the thermal-difference states. We identify the parameter values for which these states have a negative …

  2. 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 …
