提出了一种利用纠缠传输和量子中继器实现多比特受控相位门（MQCPG）的方案。在实现过程中，采用了单比特旋转操作、受控非门和量子相位门等局部变换，实现了量子门的远程实现。事实证明，MQCPG可以在独立的空间代理之间实现，具有接近单位的保真度和成功概率。此外，所需的经典信息消费的建议的场景。此外，一些有吸引力的问题进行了讨论，包括本建议的特点和实验的可行性，根据现有的技术。值得注意的是，它揭示了我们的建议本质上访问几个平凡的功能在于突破了限制，错误概率与通道的长度呈指数级的门的实现过程中，以及与今天的实验技术的兼容性。
A feasible proposal is explored to remotely perform a family of multi-qubit controlled-phase gates (MQCPG), with the aid of entanglement transfer and quantum repeater. To remotely realize the gates, some local transformations, including single-qubit rotating operation, controlled-NOT gate and quantum phase gate, are employed during the realization. It turns out that MQCPG can be implemented among separate spatially agents with nearly unit fidelity and success probability. Besides, required classical information consumption of the proposed scenario is worked out. Furthermore, some attractive issues are discussed including the feature of present proposal and the experimental feasibility based on current technologies. Remarkably, it is revealed that our proposal essentially accesses to several nontrivial features lying in breaking through the limitation that error probability scales exponentially with the length of the channel in the course of the realization of the gates, and well compatibility with today’s experimental technologies.
