钻石中的色心是很有希望用于量子计算和量子网络的自旋量子比特。在光子介导的纠缠分配方案中，光接口的效率最终决定了此类系统的可扩展性。耦合到发射器的纳米级光学腔构成了一个强大的自旋-光子界面，可以提高自发辐射率和光子提取效率。在这项工作中，我们介绍了直接在块状金刚石中制备具有高品质因数和立方波长模式体积的二维光子晶体板条纳米腔。这个平面平台提供了可扩展性，并极大地扩展了钻石中经典和量子纳米光子学的工具包。
Color centers in diamond are promising spin qubits for quantum computing and quantum networking. In photon-mediated entanglement distribution schemes, the efficiency of the optical interface ultimately determines the scalability of such systems. Nano-scale optical cavities coupled to emitters constitute a robust spin-photon interface that can increase spontaneous emission rates and photon extraction efficiencies. In this work, we introduce the fabrication of 2D photonic crystal slab nanocavities with high quality factors and cubic wavelength mode volumes -- directly in bulk diamond. This planar platform offers scalability and considerably expands the toolkit for classical and quantum nanophotonics in diamond.
