We propose and experimentally demonstrate a phase-sensitive continuous variable quantum key distribution system with improved secure key rate, utilizing multimode coherent states, phase-conjugated subcarrier modulation, and phase-sensitive detection. The experimental results confirm the higher secure key rate and better excess noise tolerance of the new scheme compared to the typical implementation of GG02.
We develop and experimentally demonstrate a phase-sensitive continuous variable quantum key distribution system with improved secure key rate. This is achieved using multimode coherent states with phase-conjugated subcarrier modulation and phase-sensitive detection. The local oscillator for phase-sensitive detection is regenerated from a polarization-multiplexed carrier wave via optical injection locking. The proposed scheme has a higher classical information capacity at a given number of received photons and exhibits a higher secure key rate when applying the security analysis of the GG02 protocol. Experimental results confirm the higher secret key rate and better excess noise tolerance of the new scheme compared to the typical implementation of GG02.(c) 2023 Chinese Laser Press
