Description

technical field

[0001] The invention belongs to the field of quantum information and laser technology, and in particular relates to a processing system and method for mixing and entanglement of continuous variable polarization and orbital angular momentum. Background technique

[0002] Quantum entanglement is one of the important resources of quantum information science, which has quantum correlation properties that classical light fields do not have. Based on the quantum entanglement effect, the information is encoded, manipulated, transmitted and processed, which effectively guarantees the security of information communication and completes tasks that cannot be accomplished by traditional classical laser communication. Since the photon has multiple degrees of freedom, the manipulation and encoding of the multi-dimensional freedom of the photon can realize the ability of parallel transmission and processing of information, which can greatly increase the information carrying...
