Performance Improvement of Underwater Continuous-Variable Quantum Key Distribution via Photon Subtraction
Considering the ocean water’s optical attenuation is significantly larger than that of Fiber Channel, we propose an approach to enhance the security of underwater continuous-variable quantum key distribution (CVQKD). In particular, the photon subtraction operation is performed at the emitt...
