Title:
QUANTUM PARAMETER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2020/253292
Kind Code:
A1
Abstract:
Disclosed is a quantum parameter amplifier, comprising a capacitor module, a first microwave resonant cavity and an inductance-adjustable superconducting quantum interference device which are connected in sequence and used for forming an oscillation amplification circuit. The superconducting quantum interference device is grounded. The quantum parameter amplifier further comprises a voltage modulation circuit and/or a second microwave resonant cavity. One end of the voltage modulation circuit is connected to the end of the superconducting quantum interference device close to the first microwave resonant cavity. One end of the second microwave resonant cavity is connected to the end of the superconducting quantum interference device close to the first microwave resonant cavity. The frequency of a pumping signal of the quantum parameter amplifier in an optimal working mode does not need to be selected as a frequency multiplication of a signal to be amplified.
