Description

Technical Field

[0001] This invention belongs to the field of key decoding technology, and particularly relates to a quantum key decoding device. Background Technology

[0002] Quantum keys, as the name suggests, are keys generated using the principles of quantum mechanics, possessing high randomness and security. In quantum key distribution, the communicating parties transmit quantum states through a quantum channel, utilizing the properties of quantum states to ensure the security of key distribution. A quantum key is a set of random numbers, and both communicating parties share the same set of quantum keys. The communication content is then transformed using these random numbers, resulting in random numbers. Since legitimate communicators have already shared the key, a legitimate receiver, upon receiving the random number, can use the key to reverse the transformation and extract the information from the randomness. Eavesdroppers, lacking the key, only receive a jumble of random numbers and cannot obtain any useful information. Therefore, quantum keys are a highly secure key, providing excellent security for communication. To perform quantum key decoding, a quantum key decoding device is required.

[0003] Chinese patent disclosure (CN114697021A) discloses an optical quantum encoding / decoding device and a quantum key distribution system. The optical quantum encoding / decoding device includes an optical coupler, a first optical circulator, an adjustable optical delay line, and an optical mirror arranged sequentially. The optical coupler is used to split an input optical pulse into at least a first sub-optical pulse and a second sub-optical pulse. The optical coupler, the first optical circulator, the adjustable optical delay line, and the optical mirror form a Segnak ring. The first and second sub-optical pulses are transmitted to the optical coupler in clockwise and counterclockwise directions along the Segnak ring, respectively, and are output by the optical coupler, generating a pair of consecutive sub-optical pulses with time delay. The adjustable optical delay line adjusts the relative time delay of the first and second sub-optical pulses, making the delay of the two sub-optical pulses transmitted clockwise and counterclockwise by the Segnak ring adjustable, thereby solving the technical problem of the non-adjustable delay of unequal-arm interferometers. While current quantum key decoding devices can decode quantum keys, they are prone to several problems during use. Firstly, there's the wiring issue. To facilitate real-time data transmission and recording, multiple data cables are required, but the available interface types and quantities are insufficient, and the interface layout is often illogical, leading to tangled wires that are difficult to separate later. Furthermore, incomplete recording of device information hinders quick analysis and resolution of malfunctions, resulting in poor overall performance in practical applications. Therefore, a quantum key decoding device is urgently needed to address these problems. Summary of the Invention
