单囚禁离子运动态与光的纠缠

Entanglement between motional states of a single trapped ion and light

F. L. Semiao, A. Vidiella-Barranco, J. A. Roversi

摘要:

我们提出了一种利用光和单个囚禁离子的振动产生Bell态的方法。陷阱本身应该被放置在一个高$Q$腔维持一个单一的模式,量化的电磁场。如果在适当的相互作用时间和适当的初始状态准备之后对离子的内部电子状态进行有条件的测量,则可以容易地产生纠缠的光运动状态。我们表明,所有四个贝尔状态可能会产生使用不同的运动边带(蓝色或红色),以及足够的离子相对相位。

英文摘要:

We propose a generation method of Bell-type states involving light and the vibrational motion of a single trapped ion. The trap itself is supposed to be placed inside a high-$Q$ cavity sustaining a single mode, quantized electromagnetic field. Entangled light-motional states may be readily generated if a conditional measurement of the ion's internal electronic state is made after an appropriate interaction time and a suitable preparation of the initial state. We show that all four Bell states may be generated using different motional sidebands (either blue or red), as well as adequate ionic relative phases.
