Quantum Control of Optically Active Artificial Atoms With Surface Acoustic Waves

Abstract

Surface acoustic waves (SAWs) are a versatile tool for realizing coherent quantum interfaces between various solid-state qubits spanning microwave to optical frequencies. Through strain, electric, or magnetic fields associated with acoustic waves, qubit states can be controlled and measured with exquisite precision for applications in quantum information processing, memory, transduction, and sensing. In this review, we discuss progress toward quantum control using surface acoustic waves coupled to optically active artificial atoms, including semiconductor quantum dots (QDs), optically addressable solid-state spins, and quantum emitters in van der Waals materials. We outline the device, material, and theoretical considerations for realizing interactions with surface acoustic waves in the quantum regime, summarize the state of the art in coupling surface acoustic waves to artificial atoms, and provide insight into the current trends and trajectory of the field.
