Multimode josephson parametric converter: coupling josephson ring modlator to metamaterial

摘要

A technique relates to operating a multimode josephson parametric converter as a multimode quantum limited amplifier. The multimode. Josephson parametric converter receives multiple quantum signals in parallel at different resonance frequencies. The multimode Josephson parametric converter amplifies simultaneously the multiple quantum signals, according to pump signals applied to the multimode Josephson parametric converter. The multiple quantum signals having been amplified at the different resonance frequencies are reflected, according to the pump signals.
