METHOD OF DISTRIBUTING SECRET KEY WITH LOW-POWER IN QUANTUM COMMUNICATION METHOD OF PERFORMING QUANTUM COMMUNICATION USING THE SAME AND QUANTUM COMMUNICATION FOR PERFORMING THE SAME

摘要

A method for distributing a quantum key includes the steps of: enabling a server to generate a cubit and transmitting the cubit to a user terminal; enabling a user terminal to encode a secret key on the cubit and loop back the cubit in which the secret key is encoded to the server when not in a security check mode; enabling the user terminal to measure the cubit when in the security check mode; and enabling the server to transmit a measurement result when the cubit is measured by a correct basis to the user terminal, if the server does not receive the loopback of the cubit. Accordingly, the present invention can reduce power consumption.
