  • Continuous-variable quantum key distribution (CV-QKD) method and system
    Patent number: 12088707
    Abstract: A continuous-variable quantum key distribution (CV-QKD) method and system is provided. The CV-QKD method includes: step 1: transmitting a quantum signal and a local oscillation signal synchronously based on time and polarization multiplexing, and performing detection to obtain detection data; and step 2: compensating for the detection data based on a phase compensation algorithm and public data. In this way, a phase can be compensated accurately in channel fading, so as to improve performance of the CV-QKD system.
    Type: Grant
    Filed: January 23, 2021
    Date of Patent: September 10, 2024
    Assignee: SHANGHAI JIAO TONG UNIVERSITY
    Inventors: Peng Huang, Shiyu Wang, Guihua Zeng
