METHOD OF DISTRIBUTING KEY IN QUANTUM COMMUNICATION METHOD OF PERFORMING QUANTUM COMMUNICATION USING THE SAME AND QUANTUM COMMUNICATION SYSTEM PERFORMING THE SAME

摘要

In the key distribution method in quantum communication, the transmitter and the receiver publicly determine the length of the seed. The transmitter and the receiver perform the predetermined protocol and perform the first information adjustment and the first confidentiality amplification on the seed to share the seed. The transmitter and the receiver generate a first random binary string and a second random binary string, respectively, based on the seed. The transmitter generates a first random bit string. The transmitter codes the first random bit string based on the first basis according to the first random binary string and transmits it to the receiver. The receiver measures a first random bit string encoded based on a second basis in accordance with the second random binary string to obtain a second random bit string.
