Vacuum-evacuated photon generation device and method using squeezed state beam and two coherent state beam

摘要

A photon generating apparatus and a photon generating method using the same are provided. The photon generating apparatus includes a first beam splitter to which a first input beam and a second input beam are inputted and outputs a first output beam and a second output beam and a second beam splitter having a first output beam and a third input And a second beam splitter into which a beam is inputted and a third output beam and a fourth output beam are outputted. Thus, it is possible to efficiently generate photons of non-total quantum state in which the vacuum state is removed.
