Abstract: A technique relates to a quantum-limited microwave amplifier. A Josephson ring modulator (JRM) is connected to a first lumped-element resonator. The first lumped-element resonator includes one or more first lumped elements. A second lumped-element resonator is connected to the JRM, and the second lumped-element resonator includes one or more second lumped elements. The JRM, the first lumped-element resonator, and the second-lumped element resonator form a Josephson parametric converter (JPC). The one or more first lumped elements and the one or more second lumped elements have a value that is the same, thereby configuring the JPC to be spectrally degenerate.

Abstract: 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.

Abstract: A technique relates to a microwave device (300). A qubit (310) is connected to a first end of a first coupling capacitor (320A) and a first end of a second coupling capacitor (320B). A resonator (305) is connected to a second end of the first coupling capacitor (320A) and a second end of the second coupling capacitor (320B). The resonator (305) includes a fundamental resonance mode. A filter (315) is connected to both the qubit (310) and the first end of the first or second coupling capacitor (320A, 320B).
