CRYOGENIC INTEGRATED CIRCUIT, INTEGRATED MODULE, AND ARRANGEMENT FOR PRODUCING AND DETECTING EXCITATION AND READOUT SIGNALS OF QUBITS

摘要

A cryogenic integrated circuit or integrated module (1201) comprises a travelling wave parametric amplifier or a Josephson parametric amplifier (1001). An oscillator (1004) is configured to produce an oscillating drive signal and to couple said oscillating drive signal into said amplifier. A signal input (1203) couples input signals into said amplifier. A biasing input (1205) couples biasing signals into said oscillator. A signal output conveys output signals from said amplifier out of the cryogenic integrated circuit or integrated module (1201).
