Researchers at Oxford have devised a broadband high efficiency frequency up-converter based on the nonlinear wave mixing mechanism in a travelling wave parametric device. The up-converter exhibits quantum-limit noise performance, high conversion efficiency and cleanly defined spectral components. Key application areas include quantum-computing, astronomical experimentation and cryogenic readout applications.
