混合量子系统结合了不同物理平台的优势，旨在实现更强大的量子信息处理设备。机械系统（例如体声波谐振器）在紧凑的尺寸内拥有多个高度相干的谐波模式，能够很好地补充超导量子电路的强非线性和快速操作能力。
研究组开发了一种基于机械谐振器的量子计算架构，在该架构中，利用一个超导量子比特对一组机械模式执行量子门操作。研究组演示了由单量子比特门和受控任意相位门组成的通用门集，并展示了它们在量子傅里叶变换和周期查找算法中的应用。这些结果显示了利用机械系统构建量子技术关键组件（如量子随机存取存储器）的潜力。

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.
