在这篇文章中,我们首次提出了远程制备单个87Rb原子内态的实验演示。我们的方法使用原子-光子纠缠作为两个量子系统之间的界面,并允许远距离制备远距离原子量子比特的任意量子态。为此,我们使用量子隐形传态协议,首先在光子上准备所需的态,然后在Bell态测量之后,转移到原子上。
In this paper, we present the first experimental demonstration of the remote preparation of an internal state of a single 87Rb atom. Our approach uses atom-photon entanglement as the interface between the two quantum systems and allows to distantly prepare an arbitrary quantum state of a distant atomic qubit. For this purpose we use the quantum teleportation protocol, where the desired state is first prepared on the photon and, after Bell state measurement, transferred to the atom.
