Abstract:
1. A method of addressing in a quantum network which includes N nodes with a star-configuration, wherein N is larger than 3, the method comprising steps of: appointing each node an address serial number; determining by a source node a transmission wavelength from a lookup table which is formed of the address serial number of each node and the transmission wavelength used between every two nodes, wherein when the number of nodes in the quantum network is odd, the total number of said transmission wavelengths is N; when the number of nodes in the quantum network is even, the total number of transmission wavelengths is N−1; transmitting from the source node to a destination node an optical quantum state signal on the determined wavelength; and determining, by the destination node, the source of the received optical quantum state signal from a lookup table by using the transmission wavelength of the received optical quantum state signal.
