Title:
量子鍵配送のための方法及びシステム
Document Type and Number:
Japanese Patent JP7440108
Kind Code:
B2
Abstract:
A method for quantum key distribution in a system comprising a plurality of data processing devices comprises: providing an initial key in a first data processing device and a second data processing device; providing, in the second data processing device, a quantum signal comprising a plurality of quantum states; determining, in the second data processing device, a plurality of quantum measurement parameters; determining, in the second data processing device, a raw signal by quantum measuring the plurality of quantum states employing the plurality of quantum measurement parameters; generating with the initial key, in the second data processing device, an encrypted signal indicating at least one the plurality of quantum measurement parameters and transmitting the encrypted signal to the first data processing device; determining, in at least one of the first data processing device and the second data processing device, a reconciled signal from the encrypted signal; determining, in at least one of the first data processing device and the second data processing device, a shared key from the reconciled signal by correcting the first reconciled signal.
