基于由量子点与双面微柱腔耦合组成的混合系统,我们研究了由另一个光子控制的错误检测光子量子路由的实现。单光子检测预示着由意外实验缺陷引起的计算错误,从而导致本方案具有单位保真度,因此该方案本质上是鲁棒的。我们讨论了该方案与当前可实现的实验参数的性能。我们的结果表明本方案是有效的。此外,我们的方案可以为未来的量子网络和分布式量子信息处理提供有前景的构建模块。
Based on a hybrid system consisting of a quantum dot coupled with a double-sided micropillar cavity, we investigate the implementation of an error-detected photonic quantum routing controlled by the other photon. The computational errors from unexpected experimental imperfections are heralded by single photon detections, resulting in a unit fidelity for the present scheme, so that this scheme is intrinsically robust. We discuss the performance of the scheme with currently achievable experimental parameters. Our results show that the present scheme is efficient. Furthermore, our scheme could provide a promising building block for quantum networks and distributed quantum information processing in the future.
