Abstract
One example includes a parametric amplifier system. The system includes an input/output (I/O) transmission line to propagate a signal tone. The system also includes a non-linearity circuit comprising at least one Josephson junction to provide at least one inductive path of the signal tone in parallel with the at least one Josephson junction. The system further includes an impedance matching network coupled to the I/O transmission line to provide impedance matching of the tone signal between the I/O transmission line and the non-linearity element.
