Problems solved by technology

[0005] Due to the electronic boards, light source boards, optical path components and detector hash settings that make up the quantum key distribution system, the testing, maintenance and management of the entire system are relatively scattered, and it is not easy to manage as a whole; and when using multiple quantum key distribution When the system forms a quantum key distribution network, the networking between the quantum key distribution systems is complex, and management and maintenance are more difficult

Embodiment 2

[0143] image 3 It is a schematic structural diagram of Embodiment 2 of a quantum key distribution system of the present invention, and the system includes:

[0144] Two quantum key distribution terminals 301 and 302 described in Embodiment 1 of the present invention.

[0145] One quantum key distribution terminal 301 acts as the sender, and the other quantum key distribution terminal 302 acts as the receiver, or two quantum key distribution terminals can act as the sender and receiver at the same time.

[0146] The network interfaces of the two quantum key distribution terminals 301 and 302 are connected through a network cable 303, providing the two quantum key distribution terminals with a data exchange channel in the process of base vector comparison, data error correction and privacy amplification.

[0147] The quantum optical fiber interfaces of the two quantum key distribution terminals are connected through an optical fiber 304, providing a channel for the two quantum...

Embodiment 3

[0154] Figure 4 It is a schematic structural diagram of Embodiment 3 of a quantum key distribution system of the present invention, and the system includes:

[0155] At least one switch 401, at least one optical switch 402, at least two quantum key distribution terminals 403 and 404 according to Embodiment 1 of the present invention, and one quantum key distribution control center 405.

[0156] Such as Figure 4 As shown, the switch 401, the optical switch 402, the quantum key distribution terminals 403 and 404 described in Embodiment 1 of the present invention, and the quantum key distribution control center 405 can form a quantum key distribution local area network. What needs to be explained here is that the number of quantum key distribution terminals is not limited to Figure 4 Two are shown, there can be more.

[0157] same Figure 5 Among them, the switch 501, the optical switch 502, the quantum key distribution terminals 503 and 504 described in Embodiment 1 of th...

Abstract

The invention discloses a quantum key distribution terminal and system, which organically integrates the optical transceiver device and the electronic board card in the quantum key distribution system into a whole through the electronic backboard, and provides a compact, integrated High-precision quantum key distribution terminal, which can realize the unified testing, maintenance and management of each component device in the quantum key distribution system, realize the integration and terminalization of the key distribution system, and use the same quantum key The distribution terminal can be flexibly networked to build a quantum key distribution system of point-to-point, LAN or metropolitan area network scale.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a quantum key distribution terminal and system. Background technique [0002] With the rapid development of quantum communication technology, Quantum Key Distribution (Quantum Key Distribution, QKD) has gradually become a mature application technology. This technology is based on the principle of quantum non-cloning and uncertainty. The key generated by it has theoretical absolute security and is mainly used in places that require a high level of confidentiality. The existing quantum key distribution hardware equipment is mainly composed of an optical transceiver and an electronic board. The optical transceiver includes a light source board, an optical path component and a detector. The electronic board is mainly used for data processing and key generation control. and key management etc. [0003] When using quantum key distribution hardware equipment, since each ...
