Title: Distant communication with Quantum hybrid-light

Abstract: Cavity-quantized optical states possessing non-regular probability distributions, formally known as quantum light, play a crucial role in modern information processing tasks. We bring forth the efficacy of optical-hybrid states, which adjoin the best of both DV and CV worlds. Alongside sharing entanglement over large distances, such states outperform DV-only and CV-only endeavors in nonlocal teleportation and loophole-free Bell experiments. Besides, it is also intriguing to understand what quantum is. Here, we develop a resource-theoretic formulation of optical nonclassicality that provides an entropic quantification of additional sampling required to simulate a quantum state. Moreover, the generic structure enables an extension of other similar theories and systems with discrete observables.
