Josephson impedance gradient parametric amplifier

This product is mainly used for amplifying specific microwave frequency band signals in extremely low temperature environments, improving the signal-to-noise ratio of signals in the signal testing link. This product can achieve gain performance of over 12dB on a bandwidth exceeding 300MHz. It can fine tune the center frequency by adjusting voltage bias and pump frequency, and can also customize the center frequency of the gain bandwidth in the 6-7GHz frequency band. This product is particularly suitable for the field of superconducting quantum computing to amplify the reading signals of multiple quantum bits, and has a very significant effect on improving the reading fidelity of quantum bits.
