Abstract

We develop theory of realization of hybrid entanglement between\ndiscrete-variable (single photon) and continuous-variable states (coherent\nstates). A highly transmissive beam splitter (HTBS) is used for interaction of\nthe ingredients. Mechanism for generating the hybrid entangled states is based\non the simultaneous displacement of the discrete-variable state on equal in\nabsolute value but opposite in sign displacement amplitudes by coherent\ncomponents, in such a way that all the information about the displacement\namplitudes is lost with subsequent registration of photons in the auxiliary\nmode. Conditions for the balanced hybrid entangled states generation are found.\nOur approach follows along lines experimentally demonstrated in Nat. Photonics\n8, 570-574 (2014).\n
