Abstract
A quantum parameter amplifier; the quantum parameter amplifier includes a capacitor module, a first microwave resonant cavity, and an inductance-adjustable superconducting quantum interference apparatus that are connected in sequence to constitute an oscillation amplifier circuit, wherein, the superconducting quantum interference apparatus is grounded; the quantum parameter amplifier further includes a voltage modulating circuit and/or a second microwave resonant cavity; one end of the voltage modulating circuit is connected with an end of the superconducting quantum interference apparatus that is close to the first microwave resonant cavity; and one end of the second microwave resonant cavity is connected with the end of the superconducting quantum interference apparatus that is close to the first microwave resonant cavity. A frequency of a pump signal that makes the quantum parameter amplifier according to the present disclosure in an optimal operation mode does not need to be selected as a multiple of a frequency of the signal to be amplified.
