Abstract

In quantum information processing, the Josephson parametric amplifier (JPA) has become a crucial tool for fast, high-fidelity readout of superconducting qubits, and for the generation of squeezed microwave radiation. However, research groups worldwide have reported unexpected nonidealities in these devices, leading to poorer than anticipated performance. Using numerical simulations complemented by experiments, the authors pinpoint oft-neglected higher-order circuit nonlinearities as the main source of these nonidealities, and provide simple, concrete steps to improve JPA performance.
