Problems solved by technology

[0004] The above research work has realized the quantum purification of atomic ensembles and solved the problem of improving the entanglement between atomic ensembles. However, once the purification operation fails in the above method, the quantum entanglement between atoms will be destroyed, and atomic entanglement needs to be re-prepared many times. To be used for entanglement purification, there is a technical problem of high cost of atomic entanglement preparation

Description

technical field [0001] The invention relates to a continuous variable entanglement distillation device between atomic ensembles, which belongs to the technical field of continuous variable entanglement distillation. Background technique [0002] In the development of quantum information science, quantum network is one of the current research hotspots. Quantum networks can consist of optical quantum channels and atomic quantum nodes. Among them, light is an ideal carrier for long-distance transmission of quantum information, and can be used to realize the interconnection between quantum nodes; atomic ensembles are one of the effective media for quantum nodes due to their advantages of large optical thickness and good coherence. The storage and processing of quantum information can be realized. Quantum entanglement can not only be used to study the basic problems of quantum mechanics, but also is the core resource for realizing quantum information. However, the effect of en...
