Coherent Diffusive Photon Gun for Generating Nonclassical States

Year: 2019

Type: article

Abstract: The authors present a family of compact, versatile, and deterministic sources of quantum light with user-selected properties. These photon guns (``PhoGs'') will enhance performance in many quantum technologies by providing a ready alternative to attenuated quantum coherent states, which are normally used for their convenience. PhoG devices are based on engineered nonlinear loss in dissipatively coupled optical waveguide networks, with the ``cheap'' attenuated coherent states as input. In different regimes, a PhoG acts either as a deterministic source of highly sub-Poissonian light, or as a source of entangled photons in different state configurations.
