Low-Loss Floquet Mode Josephson Traveling-Wave Parametric Amplifiers with Broadband Near-Ideal Intrinsic Quantum Efficiency

ORAL

Abstract

We experimentally demonstrate a low-loss, Floquet mode traveling-wave parametric amplifier (Floquet TWPA) using a superconducting qubit compatible aluminum process. With 20 dB gain and less than 1 dB of insertion loss over a several GHz bandwidth, our Floquet TWPAs are ideal for a wide range of information-critical applications such as multiplexed qubit readout. We present noise characterization and superconducting qubit measurement using a Floquet TWPA.
