基于Wu et al.'的原始想法（物理Lett. A 372：2802，2008），我们提出了一种远程实现多量子比特量子相位门的方案。在纠缠交换、经典通信和量子中继器的辅助下，多量子比特量子相位门可以近乎完美地实现。强调了我们的方案可以克服在门的实现过程中错误概率与沟道长度成指数关系的限制。
Based on Wu et al.’s original idea (Phys. Lett. A 372:2802, 2008), we propose a scheme to remotely implement multi-qubit quantum phase gates. With the assistance of entanglement swapping, classical communication and quantum repeater, multi-qubit quantum phase gates can be realized perfectly nearly. It is emphasized that our proposal can overcome the limitation that error probability scales exponentially with the length of the channel during the realization of the gates.
