The power of quantum computers is expected to be realized only once the individual components, the quantum bits (or qubits), can be linked up into a large-scale system. Success also requires that the quantum information be reliably transported from one part of the system to another for processing. With several different approaches being undertaken, Schuetz et al. propose that surface acoustic waves could propagate the quantum information across a diverse set of solid-state architectures. With piezoactive materials forming a connected network between qubits, they show theoretically that the quanta should be able to “surf” the acoustic excitations for a variety of on-chip implementations of a quantum computer.
