Beschreibung
Zusammenfassung:	An optical quantum state converter comprises an optical fiber input port configured to receive an optical signal comprising an optical quantum state at a first wavelength from an optical source. An optical combiner having a first input is coupled to the optical fiber input port. An optical pump source having an output that is coupled to a second input of the optical combiner provides an optical pump signal at a pump signal wavelength to a second input of the combiner. A nonlinear optical waveguide having an input that is coupled to an output of the optical combiner converts the optical quantum state at the first wavelength to an optical quantum state at a second wavelength determined by the optical pump signal.
