Decoherence of surface phonons in a quantum acoustic system
Decoherence of surface phonons in a quantum acoustic system
Phononic resonators are becoming increasingly important in quantum information science, both for applications in quantum computing, communication, and sensing as well as in experiments investigating fundamental physics. Here, we study the decoherence of phonons confined in a surface acoustic wave (SAW) resonator strongly coupled (g/2π≈9MHz) to a superconducting transmon qubit. …
