Free space continuous variable Quantum Key Distribution with discrete phases

Physics Open, 2023
Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authenticated users.

Continuous-Variable Quantum Key Distribution Over Air Quantum Channel With Phase Shift

IEEE Access, 2020
Continuous-variable quantum key distribution (CV-QKD) over air quantum channel enables to provide unconditional information security, which is the one of most promising techniques for information wireless transfer. Since the air channel is of fluctuation

Quantum Forbidden-Interval Theorems for Stochastic Resonance [PDF]

, 2008
We extend the classical forbidden-interval theorems for a stochastic-resonance noise benefit in a nonlinear system to a quantum-optical communication model and a continuous-variable quantum key distribution model.
