Abstract
Spin qubits are situated in mechanical resonators that are acoustically coupled with acoustic waveguides. The acoustic waveguides provide frequency dependent phonon propagation selected so that mechanical resonators adjacent to a selected mechanical resonator are acoustically coupled to the selected mechanical resonator in different acoustic frequency ranges. This configure permits directional transfer of quantum states between spins in spin-mechanical resonator and provides a scalable platform for spin-based quantum computing.
