Frequency-Modulated Microwave Drives for Single- and Two-Qubit Gates

ORAL

Abstract

High-fidelity single- and two-qubit gates are one of the fundamental requirements in the pursuit of large-scale fault-tolerant quantum computing. In this work, we examine the architecture of fixed-frequency superconducting qubits and couplers driven by microwaves. We introduce a new type of gate where the microwave drive frequency is modulated through deliberate design, a technique also known as chirping. By leveraging Floquet theory, we analyze and design these drives for optimal performance. Our method is validated through numerical simulations, and we discuss progress toward realizing high-fidelity gates using frequency-modulated microwave drives.
