Coupling superconducting qubits to traveling surface acoustic wave phonons

ORAL

Abstract

Surface acoustic wave (SAW) devices are heavily used in classical signal processing applications. SAWs have also been proposed as a method to coherently couple disparate solid-state quantum systems, such as superconducting and semiconducting qubits[1-4]. Recently the quantum control of phonons in a SAW resonator has also been demonstrated[5]. In this talk, we report the experimental development of a device coupling two superconducting qubits through SAW phonons. The transduction of the energy quantum is performed by a unidirectional SAW transducer. We examine the influence of the material properties, coupling strategy, acoustic velocity and design on the performance of the state transfer.
