Description

We design, fabricate and experimentally investigate a parametric amplifier based on the nonlinear inductance of Josephson junctions embedded into a superconducting resonator. The conventional design is based on a strongly coupled coplanar waveguide quarter-wave resonator terminated by a single SQUID. The weakly non-linear resonator is driven close to a bistable state where the system's response is highly sensitive to small perturbations. We performed four-wave-mixing experiments and obtained signal gain of up to 20 dB. The measured device performance is compared with theoretical expectations.
