Mitigating transients of flux pulse in a quantum processor using novel pulse shape

ORAL

Abstract

Quantum processors often rely on precisely controlled flux pulses for both frequency tuning and two-qubit gate operations. However, these pulses are susceptible to distortions caused by electrical components such as bias tees and attenuators. Characterizing and correcting these distortions for each flux line is both time consuming and cumbersome. We present a class of flux pulses designed to minimize the impact of transients in flux lines, enabling transient mitigation without the need for detailed characterization. Our approach is validated through experiments on a flux-tunable coupler and qubit architecture.
