论文摘要
我们研究了具有相同振动离子Qubits的单模腔中的多光子共振和多离子激发，从而使离子内部状态，腔模式和离子的振动运动之间的三方相互作用实现了三方相互作用。在特定的谐振条件下，我们分别为三光子和三启示案例得出有效的哈密顿量，并发现可以通过振动模式调整有效耦合能的大小，从而可以在实验中对离子 - 光子耦合进行操纵。此外，我们分析了我们提出的设置的系统动力学，并在这些系统中表现出具有耗散效应的系统中的Rabi振荡行为。我们建议我们的系统作为探索纠缠多Qubit物理的多功能平台。
We investigate the multi-photon resonance and multi-ion excitation in a single-mode cavity with identical vibrating ion-qubits, which enables the tripartite interaction among the internal states of ions, the cavity mode and the ions' vibrational motion. Under particular resonant conditions, we derive effective Hamiltonians for the three-photon and the three-excitation cases, respectively, and find that the magnitude of the effective coupling energy can be tuned through the vibration mode, allowing for manipulations of ion-photon coupling in experiments. Furthermore, we analyze the system dynamics of our proposed setups and demonstrate the Rabi oscillation behaviors in these systems with dissipation effects. We propose our system as a versatile platform for the exploration of entangled multi-qubit physics.
