Abstract
Section titled āAbstractāWe propose a universal, on-chip quantum transducer based on surface acoustic\nwaves in piezo-active materials. Because of the intrinsic piezoelectric (and/or\nmagnetostrictive) properties of the material, our approach provides a universal\nplatform capable of coherently linking a broad array of qubits, including\nquantum dots, trapped ions, nitrogen-vacancy centers or superconducting qubits.\nThe quantized modes of surface acoustic waves lie in the gigahertz range, can\nbe strongly confined close to the surface in phononic cavities and guided in\nacoustic waveguides. We show that this type of surface acoustic excitations can\nbe utilized efficiently as a quantum bus, serving as an on-chip, mechanical\ncavity-QED equivalent of microwave photons and enabling long-range coupling of\na wide range of qubits.\n
