Simulation and Design of Quantum Phase Slip Junction-Based Parametric Amplifiers

We have designed a traveling-wave parametric amplifier based on quantum phase-slip junctions. This amplifier has a LC-ladder nonlinear transmission line structure, and acts as a dual to the Josephson traveling-wave parametric amplifier. We use WRspice simulations to design and analyze the quantum phase-slip junction-based traveling-wave parametric amplifier. Our simulations capture parametric amplification by demonstrating frequency mixing, signal gain, and generation of an idler tone. In additional simulations, we control various circuit parameters: the quantum phase-slip junctions, critical voltage, quantum phase-slip junction count, and bias voltage. We report and discuss these parameters' effects on the amplifier's signal gain. We compare these performance metrics with those from simulations of a typical Josephson traveling-wave parametric amplifier.
