A Superconducting Quantum Interference Device Model for the Design and Optimization of Quantum-Limited Microwave Amplifiers in Harmonic Balance Simulators

Abstract

We present a dc superconducting quantum interference device (dc-SQUID) model for the design and optimization of quantum-limited parametric amplifiers. These devices are critical for superconducting quantum computing and do not currently have comprehensive models that designers can use to simulate their circuits in standard circuit simulators. Our model has been implemented and tested in the Advanced Design Systems (ADS) simulation software and validated against analytical predictions.
