| Abstract: Various technologies for performing continuous-variable (CV) and
discrete-variable (DV) quantum key distribution (QKD) with integrated
electro-optical circuits are described herein. An integrated DV-QKD
system uses Mach-Zehnder modulators to modulate a polarization of photons
at a transmitter and select a photon polarization measurement basis at a
receiver. An integrated CV-QKD system uses wavelength division
multiplexing to send and receive amplitude-modulated and phase-modulated
optical signals with a local oscillator signal while maintaining phase
coherence between the modulated signals and the local oscillator signal. |
