Title:
CONTINUOUS VARIABLE QUANTUM KEY DISTRIBUTION PHASE COMPENSATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/212461
Kind Code:
A1
Abstract:
The present invention relates to a continuous variable quantum key distribution (CVQKD) using an asynchronous local oscillator (LO), and relates to a system for performing a phase compensation by means of: a method by which a receiver (Bob) estimates an LO phase and uses a feedback by using a pilot signal from a transmitter (Alice); and a method by which the receiver (Bob) measures quantum state data by using the LO having a random phase and estimates the LO phase through a multi-dimensional reconciliation (MDR) and performs the feedback on the same.
