High Dynamic Range Josephson Parametric Amplifiers (Google Quantum AI & Others)


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 ... » read more
