论文摘要
可以直接与光纤网络和量子记忆直接集成的形状单光子的有效,可扩展的来源是量子信息科学中许多方案的核心。我们演示了具有高效率(检测效率= 14.9%)和纯度($ g^{(2)}(0)= 0.0168 $)的任意时间形状的单光子脉冲的确定性来源,以及在高度指导的钻机中,最多可连续检测到的单个光子的单光子在高度检测到的单个光子中,最多可连接单光子。结合先前证明的自旋式纠缠门,该系统可以在相关光子(例如群集状态)的按需生成中生成,并可以用作量子信息的鲁棒传输和处理的资源。
An efficient, scalable source of shaped single photons that can be directly integrated with optical fiber networks and quantum memories is at the heart of many protocols in quantum information science. We demonstrate a deterministic source of arbitrarily temporally shaped single-photon pulses with high efficiency (detection efficiency = 14.9%) and purity ($g^{(2)}(0) = 0.0168$) and streams of up to 11 consecutively detected single photons using a silicon-vacancy center in a highly directional fiber-integrated diamond nanophotonic cavity. Combined with previously demonstrated spin-photon entangling gates, this system enables on-demand generation of streams of correlated photons such as cluster states and could be used as a resource for robust transmission and processing of quantum information.
