摘要
The invention provides a multi-photon entanglement light source, and aims at outputting macro-scale multi-photon multi-difficulty entanglement light. The multi-photon entanglement light source comprises a single-mode laser and an adjustment assembly, wherein the single-mode laser is used for bidirectionally outputting two beams of laser; and the adjustment assembly is arranged on a light path of the two beams of laser and is used for adjusting laser beam volumes of the two beams of laser to be smaller than a coherent volume of the single-mode laser, and adjusting laser beam areas of the two beams of laser to be smaller than a coherent area of the single-mode laser so as to output macro-scale multi-photon multi-difficulty entanglement light. Visibly, the multi-photon entanglement light source is capable of generating multi-photon multi-difficulty entanglement light, so as to satisfy the requirement of multi-photon entanglement, thereby improving the signal to noise ratio of quantum detection and solving the quantum de-coherence problems in multiple fields of quantum information technologies such as quantum calculation and the like.
