Violating Bell inequality using weak coherent states
arXiv:2307.11123 · doi:10.1364/OL.441499
Abstract
We present an experimental investigation of two-photon interference using a continuous-wave laser. We demonstrate the violation of the CHSH inequality using the phase randomized weak coherent states from a continuous wave laser. Our implementation serves as an approach to reveal the quantum nature of a source that is considered to be a classical source.
