Surface acoustic waves (SAW) in piezo­active materials offer a versatile
means to address, manipulate and couple different solid­-state qubits.
We show that state­-of­-the­-art SAW resonators allow to
reach the strong coupling regime for several well­-studied qubits,
including quantum dots, trapped ions, nitrogen­ vacancy centers. In
combination with acoustic waveguides, this system can be utilized
efficiently as a quantum bus, serving as an on­-chip, mechanical
cavity­QED equivalent and enabling long­-range coupling of a wide range
of qubits.
