popularity

A technical paper titled “Readout of a quantum processor with high dynamic range Josephson parametric amplifiers” was published by researchers at Google Quantum AI, University of Massachusetts, Auburn University and UCSB.

“We demonstrate a resonant Josephson parametric amplifier that achieves the bandwidth performance of a matched JPA and a hundred-fold increase in saturation power,” states the paper.
