Yuangang Deng, Tao Shi, Su Yi

摘要:

对单个声子的量子操纵可以为研究基础物理和创建量子信息科学的创新平台提供新的资源。在这里,我们提出了产生与囚禁原子运动相关的强关联声子束的量子态。我们的计划在原子-声子共振制度,其中的能谱表现出很强的非谐性,使不同的声子数的能量本征态可以很好地解决在参数空间。与较早的计划在远色散制度,这里产生的束态包含一个大的稳态声子数。因此,所提出的系统可以用作高质量的多声子源。我们的研究结果开辟了利用长寿命运动声子作为量子资源的可能性,这将为量子精密测量的应用提供一个广阔的物理社区。

英文摘要:

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.
