Description

Technical Field

[0001] The invention belongs to the field of quantum communication and network technology, and relates to a quantum router used in an ultra-secure communication network. Background Art

[0002] With the rapid development of science and technology, especially the continuous progress in the field of quantum computing, traditional encryption methods are facing unprecedented challenges. Although traditional encryption technologies, such as symmetric encryption and asymmetric encryption, play an important role in the current field of information security, their security depends on the complexity of calculations. Quantum computers, due to their powerful parallel computing capabilities, can crack these traditional encryption algorithms in a short time. This means that as quantum computers gradually mature, the existing encryption system will be difficult to resist attacks from quantum computing, and information security faces serious threats.

[0003] In this context, quantum communication technology has gradually attracted attention. Quantum communication uses the basic principles of quantum mechanics, such as quantum superposition and quantum entanglement, to achieve a communication method that cannot be eavesdropped or cracked. In particular, quantum key distribution technology can generate and distribute quantum keys between communicating parties to encrypt and decrypt transmitted information. Since quantum states undergo irreversible changes when measured, any eavesdropping on quantum keys will be immediately discovered, thus ensuring the absolute security of communication.

[0004] However, existing quantum communication systems are mainly used for point-to-point communication. This mode performs well in achieving small-scale, single-link secure communication, but faces many technical challenges when building larger-scale quantum communication networks. Specifically, in large-scale networks, the routing and management of quantum information is a complex and critical issue. The transmission process of quantum information requires ensuring the stability of the quantum state, which is easily disturbed by factors such as environmental noise and equipment defects, making the transmission of quantum information in large-scale networks difficult. In addition, the generation, maintenance and distribution of quantum entangled states are also an important problem, because quantum entangled states have extremely high requirements for the transmission path and environment, and any slight interference will lead to the destruction of the entangled state, thereby affecting the accuracy and security of information transmission.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a quantum router that can support large-scale quantum communication networks. This router must not only be able to efficiently manage and transmit quantum information in complex networks, but also have the functions of quantum error correction and quantum state protection to resist the influence of external interference on quantum information. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the present invention provides a quantum router for an ultra-secure communication network.
