| Abstract: | Hybrid quantum systems combine the advantages of different physical platforms with the goal of realizing more powerful quantum information processing devices. Mechanical systems, such as bulk acoustic wave resonators, feature many highly coherent harmonic modes in a compact footprint, complementing the strong nonlinearities and fast operation of superconducting quantum circuits. We developed an architecture for mechanical resonator–based quantum computing in which a superconducting qubit is used to perform quantum gates on a collection of mechanical modes. We demonstrate a universal gate set composed of single-qubit gates and controlled arbitrary-phase gates and showcase their use in the quantum Fourier transform and period-finding algorithms. These results show the potential of using mechanical systems to build crucial components for quantum technologies, such as quantum random-access memories. Editor's summary: Several platforms are being pursued for quantum information processing and quantum computing. Hybrid systems offer the ability to combine the desirable features of various components for improved overall performance. Yang et al. introduce a mechanical-based architecture for universal quantum computing in which a quantum memory unit composed of mechanical modes of an acoustic resonator is operated on by a superconducting qubit processor. The implementation of a universal set of single- and two-qubit gates, along with their use in quantum algorithms, illustrate the potential for mechanical systems as components in quantum technologies. —Ian S.
