利用线性光学元件产生纠缠光子态的可行性

The feasible generation of entangled photon states by using linear optical elements

XuBo Zou, K. Pahlke, W. Mathis

摘要:

我们提出了一个可行的方案,以可控的方式产生偏振纠缠光子态$\frac{1}{\sqrt{2}}(|H>|V>+|V>|H>)$。该方案需要单光子源、线性光学元件和光子探测器。它产生了空间分离的光子的纠缠。相互作用发生在光子探测器中。我们还证明了同样的想法可以用来产生纠缠的$N$ -光子态$\frac{1}{\sqrt{2}}(|0,N>+|N,0>)$

英文摘要:

We present a feasible scheme to produce a polarization-entangled photon states $\frac{1}{\sqrt{2}}(|H>|V>+|V>|H>)$ in a controllable way. This scheme requires single-photon sources, linear optical elements and photon detectors. It generates the entanglement of spatially separated photons. The interaction takes place in the photon detectors. We also show that the same idea can be used to produce the entangled $N$-photon state $\frac{1}{\sqrt{2}}(|0,N>+|N,0>)$
