Abstract

The present application discloses a QKD method, device and system. Each QKD device in the QKD system includes a QKD control sub-device and at least one QKD execution sub-device. The QKD execution sub-device provides multiple quantum hardware devices, which can meet the user's needs for quantum keys generated based on different physical realization principles. QKD controls the sub-device, and can control the quantum hardware device required by QKD to execute the sub-device call, and generate the required quantum key. Based on the QKD control sub-device and QKD execution sub-device, the separation of control logic and hardware implementation is realized, and the QKD technical solution with good flexibility and high scalability is suitable for the diverse needs of users.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a QKD method, device and system. Background technique [0002] Quantum communication is a new communication technology that combines quantum theory and information theory, which can realize high-performance communication by using quantum effects under the physical limit. At present, the practical quantum communication technology is called quantum key distribution (Quantum Key Distribution, QKD) technology, and its equipment foundation is the QKD system based on the quantum key distribution protocol. The QKD system usually includes a local QKD device and a peer QKD device, and the local QKD device and the peer QKD device communicate through the QKD network and the classical communication network to realize quantum key distribution. [0003] At present, the types of QKD protocols supported by different quantum hardware devices are different. If the quantum ...
