Abstract

The invention discloses a quantum communication system based on wavelength division multiplexing encoding and key storage conversion, realizes multi-wavelength channel quantum key compilation through wavelength division multiplexing technology, and performs multi-wavelength channel quantum key parallelization through a single communication optical fiber Transmission, realize multi-channel quantum key interpretation through wavelength division multiplexing technology; use physical domain or information domain method to convert multi-wavelength channel parallel quantum key sequence into single-channel serial quantum key sequence, realize "parallel-serial Conversion of quantum key speed upgrade"; according to the technical idea of ​​quantum key saturation distribution storage, quantum key according to classical communication needs, construct full-time quantum key distribution (that is, endless distribution and storage of quantum key) and The rate adaptation mechanism of non-full-time classical communication (classical communication includes business mode and standby mode in actual cases), finally realizes high-speed quantum communication that can support higher service levels.

Description

technical field [0001] The invention belongs to the technical field of quantum communication, and relates to a quantum communication system based on wavelength division multiplexing encoding and key storage conversion, in particular to a quantum key distribution and transmission of multi-wavelength channels realized by using wavelength division multiplexing technology, through the quantum The key analysis storage technology converts the multi-channel parallel quantum key sequence into a single-channel serial quantum key sequence, and utilizes the difference in working time between the quantum key distribution system and the classical communication system to realize the high-speed quantum communication technology of rate adaptation. Background technique [0002] Quantum communication technology, based on the Heisenberg uncertainty principle, the principle of inseparability of quantum states and the principle of non-replication of quantum states, is currently recognized as a co...
