Document Type and Number:
WIPO Patent Application WO/2021/159947
Kind Code:
A1
Abstract:
The present invention provides a continuous variable quantum key distribution method and system. The method comprises: step 1, performing synchronous transmission on a quantum signal and a local oscillation signal according to time and polarization multiplexing, and performing detection to obtain detection data; and step 2, compensating the detection data according to a phase compensation algorithm and public data. According to the present invention, a phase can be accurately compensated in the case of channel fading, and the performance of the continuous variable quantum key distribution system is improved.
