摘要:

我们提出了一种新的实现双量子位光子相位门的协议。在我们的方法中,π相位是通过将两个单光子映射到具有费米子特征的原子激发态并交换它们的位置来获得的。费米子激发被实现为自旋链中的自旋波,而光子存储技术提供了光子和自旋波之间的界面。可能的缺陷和实验系统适合实现门进行了讨论。

英文摘要:

We propose a new protocol for implementing the two-qubit photonic phase gate. In our approach, the pi phase is acquired by mapping two single photons into atomic excitations with fermionic character and exchanging their positions. The fermionic excitations are realized as spin waves in a spin chain, while photon storage techniques provide the interface between the photons and the spin waves. Possible imperfections and experimental systems suitable for implementing the gate are discussed.
