在这项工作中,我们描述了一个简单的模块,可以无处不在的量子信息为基础的应用程序。基本模块包括嵌入在光学腔中的钻石中的单个NV中心,其中腔介导光子和电子自旋之间的相互作用(实现纠缠分布和有效读出),而核自旋构成能够存储和处理量子信息的长寿命量子存储器。我们讨论了如何连接模块的网络可以用于分布式计量,通信和计算应用。最后,我们调查了可能使用的替代钻石中心(SiV/GeV)的模块内,并说明潜在的优势。
In this work, we describe a simple module that could be ubiquitous for quantum information based applications. The basic modules comprises a single NV- center in diamond embedded in an optical cavity, where the cavity mediates interactions between photons and the electron spin (enabling entanglement distribution and efficient readout), while the nuclear spins constitutes a long-lived quantum memories capable of storing and processing quantum information. We discuss how a network of connected modules can be used for distributed metrology, communication and computation applications. Finally, we investigate the possible use of alternative diamond centers (SiV/GeV) within the module and illustrate potential advantages.
