Abstract
An apparatus and method for multi-user quantum key distribution. The method for multi-user quantum key distribution is performed using a multi-user quantum key distribution apparatus and a quantum key client device, and includes generating, by the multi-user quantum key distribution apparatus, transmission qubit pairs based on a key bit string of a shared key to be distributed to the quantum key client device, measuring, by the quantum key client device, the transmission qubit pairs, received from the multi-user quantum key distribution apparatus through a quantum channel, based on a measurement basis, verifying security of the quantum channel using the transmission qubit pairs, and if the security has been verified, decoding qubit measurement values of the transmission qubit pairs into the shared key.
