论文摘要
光学域中的国家保留频率转换是量子信息处理和通信的许多配置中的必要组件。到目前为止，非线性晶体用于此目的。在这里，我们报告了一种基于密集的分子氢气中的连贯的反stokes拉曼散射（CAR）的新方法。这个四波混合过程避免了晶体特性所施加的局限性，它本质上是宽带，并且不会产生不希望的背景。我们通过将光子从434 nm转换为370 nm来证明这种方法，并证明它们的极化得以保留。
State-preserving frequency conversion in the optical domain is a necessary component in many configurations of quantum information processing and communication. Thus far, nonlinear crystals are used for this purpose. Here, we report on a new approach based on coherent anti-Stokes Raman scattering (CARS) in a dense molecular hydrogen gas. This four-wave mixing process sidesteps the limitations imposed by crystal properties, it is intrinsically broadband and does not generate an undesired background. We demonstrate this method by converting photons from 434 nm to 370 nm and show that their polarization is preserved.
