Josephson Traveling Wave Parametric Amplifiers with Plasma oscillation phase-matching
Emil Rizvanov, Samuel Kern, Pavol Neilinger +1
High gain and large bandwidth of traveling-wave parametric amplifier exploiting the nonlinearity of Josephson Junctions can be achieved by fulfilling the so-called phase-matching c…
