Quantum optical communications receiver

A quantum optical communications receiver, comprising:

• a non-linear waveguide formed of a nonlinear material and having at least one reflective interface disposed proximate a first end of the waveguide;
• a pump coupled to inject pump photons at a first wavelength associated with a first energy into the first end of the waveguide;
• a coupling mechanism configured to receive an incoming signal and communicate the incoming signal to a second end of the waveguide, the incoming signal comprising injected quantum entangled signal and idler photons;
• the nonlinear waveguide performing optical parametric amplification upon the incoming optical signal in a quantum photonic process that generates additional signal and idler photons to thereby boost the intensity of the incoming signal through classical wave interference;
• wherein the injected quantum entangled photons interact with the pump photons to create phase conjugate photons, and wherein the summation of respective electric fields of the pump photons and the phase conjugate photons produce an amplitude modulated signal and idler pair;
• a photodetector coupled for communication with the coupling mechanism and operates to convert the amplitude modulated signal and idler pair into an electrical signal defining the output of the communications receiver.
