Title:
METHOD AND SYSTEM FOR ERROR CORRECTION IN QUANTUM CRYPTOGRAPHY COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2024/019570
Kind Code:
A1
Abstract:
A method for quantum cryptography communication between a first communication device and a second communication device may comprise: a quantum communication step in which, when the first communication device transmits a first information sequence generated by randomly modulating the phase or polarization of photons to the second communication device, the second communication device generates a second information sequence on the basis of the first information sequence; and a post-processing step for adjusting the first information sequence and the second information sequence to be the same on the basis of an error correction mode selected on the basis of a predetermined criterion. The error correction mode can be classified according to the decoder of parity information.
