More Information
Summary:The invention relates to the field of quantum cryptography and in particular to continuous-variable quantum key distribution (CV-QKD). The invention refers to a method of executing coherent optical communication of quantum information between an emitter (130) and a distant receiver (110) connected by two optical channels (125, 145) using continuous-variable quantum cryptography with suppression of Brillouin scattering distortions, wherein the receiver (110) comprises a CW laser (111). The invention also relates to a corresponding system.
