我们提出了一个能够对单光子混合纠缠态进行完整Bell态分析的方案。我们的单光子状态被编码在偏振和频率自由度中。该方案由偏振分束器、半波片、移频器和独立的波分复用器组成，在现有技术条件下是可行的。我们还表明，与此设置，我们可以执行完整的双光子贝尔态分析计划的偏振自由度。此外，它还可以用来执行不同自由度之间的隐形传态方案。这种设置可以在当前的量子通信中得到广泛的应用。
We propose a scheme capable of performing complete Bell-state analysis for a single-photon hybrid entangled state. Our single-photon state is encoded in both polarization and frequency degrees of freedom. The setup of the scheme is composed of polarizing beam splitters, half wave plates, frequency shifters, and independent wavelength division multiplexers, which are feasible using current technology. We also show that with this setup we can perform complete two-photon Bell-state analysis schemes for polarization degrees of freedom. Moreover, it can also be used to perform the teleportation scheme between different degrees of freedom. This setup may allow extensive applications in current quantum communications.
