摘要
自从量子纠缠态及隐性传态理论提出以来,量子纠缠技术和隐性传态技术得到了迅速发展。量子隐性传态在技术上保证了量子通信的绝对安全,量子隐性传态是基于量子纠缠交换提出的。文章阐述了量子隐形传态及量子纠缠交换的基本理论,给出了一种基于Bell态实现量子纠缠交换的量子回路,该回路结构简单,易于实现。
Quantum entangled and quantum teleportation technologies have achieved great progress since the advancement of quantum teleportation theory has been proposed. Quantum teleportationguarantees the absolute security of quantum communication in technology. Quantum entanglement swapping is proposed on the based of quantum teleportation. This paper gives description of quantum teleportation and entanglement swapping theory, proposes a quantum circuit of entanglement swapping based on Bell state. This circuit has simple structure and can be realized easily.
