示出了通过使用三个不同的基本波长并对非线性介质的谐振进行单独解调来实现高效的连续波四波混频。可以产生高达6 μW的121 nm真空紫外光，这相当于效率提高了三个数量级。这打开了量子信息处理领域的里德堡纠缠的被困离子。
Efficient continuous-wave four-wave mixing by using three different fundamental wavelengths with individual detunings to resonances of the nonlinear medium is shown. Up to 6 μW of vacuum ultraviolet light at 121 nm can be generated, which corresponds to an increase of three orders of magnitude in efficiency. This opens the field of quantum information processing by Rydberg entanglement of trapped ions.
