量子纠缠度放大器
Quantum entanglement degrees amplifier
摘要：
纠缠态的量子纠缠度随着传输距离的增加而变小，如何保持纠缠态的纯净性是量子通信中的难题。本文利用一维光子晶体设计了一种新型的纠缠度放大器，类似于经典电磁通信中的中继站。我们发现，当双光子和三光子纠缠态通过光子晶体时，它们的纠缠度可以被放大，从而使纠缠态可以远距离传播，真正实现量子通信。
英文摘要：
The quantum entangled degrees of entangled states become smaller with the transmission distance increasing, how to keep the purity of quantum entangled states is the puzzle in quantum communication. In the paper, we have designed a new type entanglement degrees amplifier by one-dimensional photonic crystal, which is similar as the relay station of classical electromagnetic communication. We find when the entangled states of two-photon and three-photon pass through photonic crystal, their entanglement degrees can be magnified, which make the entanglement states can be long range propagation and the quantum communication can be really realized.
