A quantum device includes a phononic crystal defined on a semiconductor substrate. Phononic cavities are defined in the phononic crystal, wherein each phononic cavity contains an implanted acceptor atom. Phononic waveguides are defined in the phononic crystal, wherein each waveguide is coupled to at least one phononic cavity. At least some phononic waveguides are arranged to provide coupling between phononic cavities and ultrasonic transducers. At least some phononic waveguides are arranged to provide coupling between different phononic cavities.
