我们提出了一个方案的受控非门之间的空间分离的氮空位（NV）中心诉诸线性光学，纠缠NV对，光子测量和经典通信的隐形传态。该方案利用了一种预示机制，以避免局部计算误差，反射系数只出现作为一个整体的系数，使该计划是固有的实验缺陷的鲁棒性。我们讨论了该方案的性能与当前的实验参数，结果表明，该方案是有效的。该方案在未来的分布式量子计算中具有广阔的应用前景。
We propose a scheme for the teleportation of a controlled-NOT gate between two spatially separated nitrogen-vacancy (NV) centers resorting to linear optical, entangled NV pairs, photon measurement, and classical communication. The scheme exploits a heralded mechanism to avoid local computational errors, and the reflection coefficients only appear as a global coefficient, so that this scheme is intrinsically robust to experimental imperfections. We discuss the performance of the scheme with current experimental parameters, the results show the present scheme is efficient. The present scheme is promising for distributed quantum computing in the future.
