论文摘要
单个声子的量子操作可以为研究基本物理学并创建量子信息科学的创新平台提供新的资源。在这里，我们建议生成与被困原子的运动相关的密切相关的声子束的量子状态。我们的方案在原子 - 光共振方案中运行，在该方案中，能量光谱表现出很强的非谐度，因此具有不同声子数量的能量本征性能量可以在参数空间中得到充分解决。与在远分散式中运行的较早计划相比，此处生成的捆绑状态包含一个较大的稳态声子编号。因此，所提出的系统可以用作高质量的多音量来源。我们的结果开辟了使用长寿命的运动声子作为量子资源的可能性，这可以为量子计量学应用程序提供广泛的物理社区。
Quantum manipulation of individual phonons could offer new resources for studying fundamental physics and creating an innovative platform in quantum information science. Here, we propose to generate quantum states of strongly correlated phonon bundles associated with the motion of a trapped atom. Our scheme operates in the atom-phonon resonance regime where the energy spectrum exhibits strong anharmonicity such that energy eigenstates with different phonon numbers can be well-resolved in the parameter space. Compared to earlier schemes operating in the far dispersive regime, the bundle states generated here contain a large steady-state phonon number. Therefore, the proposed system can be used as a high quality multiphonon source. Our results open up the possibility of using long-lived motional phonons as quantum resources, which could provide a broad physics community for applications in quantum metrology.
