Abstract
A METHOD FOR QUANTUM NETWORK RELAY INTRODUCES A NEW PROTOCOL OF RELAYING A KEY BY USING DETERMINISTIC QUANTUM KEY DISTRIBUTION FOR SEVERAL PARTIES. THE NUMBER OF KEY GENERATED CAN BE MAINTAINED FROM THE BEGINNING TO THE END AND WILL NOT BE AFFECTED BY THE NUMBER OF NODES IN THE NETWORK. THE METHOD INCLUDES THE STEPS OF PROVIDING A SHORT SECRET SEED KEY (11) AND EXPANDING THE SEED KEY TO A LONGER KEY (12) FOR GENERATING THE LENGTH WHICH IS TO BE USED AS THE MEASUREMENT BASIS (13). THE LENGTH, L OF THE KEY IS MAINTAINED DURING EVERY TRANSMISSION. THE PROCESS CONTINUES UNTIL THE RECEIVER NODE (23) RECEIVES L NUMBER OF QUBITS.
