Abstract

The invention discloses a quantum sensing networking method based on a wavelength division multiplexing entangled light source, and the method achieves the output of multi-wavelength entangled photons in frequency domain comb distribution through the spontaneous nonlinear effect in a nonlinear microcavity. Every two paired entangled single photons with equal frequency intervals are distributed to different point positions through a mature dense wavelength division multiplexing system in a classical optical fiber communication system, quantum sensors represented by wavelength-independent quantum interferometers are arranged at the different point positions, and networking interconnection of the quantum sensors is achieved through quantum entanglement distribution. Sensing information of all point locations in the quantum sensing network can be obtained from any point location, and leading-edge applications such as distributed cooperative sensing and the like are achieved. According to the invention, the independent quantum network server, the multi-point distributed quantum interferometer and the on-demand controlled single-photon detector are utilized, the topology variable distributed quantum sensing network function is realized, the application range of quantum communication and a quantum network is expanded, and a solution is provided for the integrated fusion of quantum Internet construction and quantum information technology.

Description

technical field [0001] The invention belongs to the interdisciplinary field of nonlinear optics, quantum detection, quantum communication and quantum network, and specifically refers to a wavelength division multiplexing entangled photon output using the spontaneous nonlinear effect in the nonlinear microcavity to realize the frequency domain comb distribution . A method for constructing a quantum sensor network through a dense wavelength division multiplexing system and a wavelength-independent quantum interferometer, in particular, a quantum sensor networking method, system and storage medium based on a wavelength division multiplexing entangled light source. Background technique [0002] Quantum is the basic unit of energy and has inseparable characteristics. Using a single quantum (such as light quantum) as an information carrier can effectively avoid the risk of separation and eavesdropping in the process of information transmission; the Heisenberg uncertainty principle ...
