Problems solved by technology

In related technologies, on the one hand, isolators, circulators, and quantum amplifiers are all independent devices, which are bulky and have serious heat loss, which is not conducive to the large-scale development of superconducting quantum computers; on the other hand, the quantum amplifier gain-bandwidth product (GBP, Gain-Bandwith Product) is smaller, that is to say, for the same quantum amplifier, GBP is determined. If a larger gain is required, it can only work in a narrower bandwidth range. If you want to work in a wider Working within the bandwidth range, the gain will be reduced, otherwise it will cause distortion of the amplified input signal

Description

technical field [0001] This application relates to but is not limited to the technical field of quantum computing, especially an on-chip non-reflective quantum amplifier with non-reciprocity. Background technique [0002] In the superconducting quantum test system, the transmission of quantum information not only needs to be amplified, but also needs to isolate the reaction of external signals. In related technologies, on the one hand, isolators, circulators, and quantum amplifiers are all independent devices, which are bulky and have serious heat loss, which is not conducive to the large-scale development of superconducting quantum computers; on the other hand, the quantum amplifier gain-bandwidth product (GBP, Gain-Bandwith Product) is smaller, that is to say, for the same quantum amplifier, GBP is determined. If a larger gain is required, it can only work in a narrower bandwidth range. If you want to work in a wider If it works within the bandwidth, the gain will be redu...
