METHOD AND APPARATUS FOR ESTIMATING BINARY BIT KEY FOR INFORMATION RECONCILIATION OF CONTINUOUS VARIABLE QUANTUM KEY DISTRIBUTION

摘要

The information receiving unit receives the transmission signal generated based on the transmission side binary bit key from the transmitting end, the error calculating unit generates at least one of the transmission signal, the pre-stored reception side binary bit key, and the predetermined parity check matrix Calculating a binary bit error indicating a difference between a transmitting-side binary bit key and a receiving-side binary bit key based on the received binary bit key and the receiving-side binary bit error; To a binary bit key estimation method for information coordination of continuous variable quantum key distribution and an apparatus therefor.
