论文摘要
我们介绍了一种在超导微波量子轴和固态人造原子的基态自旋系统之间进行高保真量子状态转导的方法，该方法是通过压电传感器连接的声音总线介导的。应用于当今的实验参数，用于在优化的语音腔中，用于超导电路盘和钻石硅空位中心，我们在MHz尺度带宽下估计量子状态转导的量子状态转导超过99 \％。通过将超导电路量子计算和人造原子的互补强度结合在一起，混合体系结构提供了具有长寿命量子记忆，高保真度测量，较大的量子数，可相互配合的量子连接性，以及通过光学量子网络通过光学量子网络提供的高量子量子器的高量符门。
We introduce a method for high-fidelity quantum state transduction between a superconducting microwave qubit and the ground state spin system of a solid-state artificial atom, mediated via an acoustic bus connected by piezoelectric transducers. Applied to present-day experimental parameters for superconducting circuit qubits and diamond silicon vacancy centers in an optimized phononic cavity, we estimate quantum state transduction with fidelity exceeding 99\% at a MHz-scale bandwidth. By combining the complementary strengths of superconducting circuit quantum computing and artificial atoms, the hybrid architecture provides high-fidelity qubit gates with long-lived quantum memory, high-fidelity measurement, large qubit number, reconfigurable qubit connectivity, and high-fidelity state and gate teleportation through optical quantum networks.
