论文摘要
多模块声系统显示出在超导量子计算中使用的希望。它们可以用作中学记忆存储，并显示出异常的连贯时间，并且表现出一种物理上紧凑的模式密度。在这里，我们在实验中证明了访问单个声学模式，而不会受到模式均匀频率间距的阻碍。我们使用侧带控制，其中将低频调制应用于Transmon量子量量量的能量。调制的幅度定义了值 - 声学模式耦合，其频率使声带侧带失调，因此可以选择性地打开或关闭交互作用，并允许对单个模式进行完整控制。
Multimode bulk acoustic systems show promise for use in superconducting quantum computation. They can serve as a medium term memory storage, with exceptional coherence times demonstrated, and they exhibit a mode density that is physically highly compact. Here we experimentally demonstrate accessing individual acoustic modes without being hindered by the uniform frequency spacing of the modes. We use sideband control where a low-frequency modulation is applied to the transmon qubit energy. The amplitude of the modulation defines the qubit-acoustic mode coupling, and its frequency detunes the acoustic sidebands, therefore enabling selectively switching on or off the interaction, and allows for a full control on the individual modes.
