论文摘要
钻石中的中性硅空位（SIV0）中心是量子网络应用的有希望的候选者，因为它们具有出色的光学特性和自旋相干性。但是，SIV0中心的稳定需要仔细的钻石宿主材料的费米水平工程，从而使技术发展具有挑战性。在这里，我们表明SIV0中心可以通过光活化的流动载体有效地稳定。即使在这种非平衡构型中，所得的SIV0中心也足够稳定，可以允许谐振光激发和光学检测到的磁共振。我们的结果为SIV0中心的按需生成以及钻石中的其他新兴量子缺陷铺平了道路。
Neutral silicon vacancy (SiV0) centers in diamond are promising candidates for quantum network applications because of their exceptional optical properties and spin coherence. However, the stabilization of SiV0 centers requires careful Fermi level engineering of the diamond host material, making further technological development challenging. Here, we show that SiV0 centers can be efficiently stabilized by photoactivated itinerant carriers. Even in this nonequilibrium configuration, the resulting SiV0 centers are stable enough to allow for resonant optical excitation and optically detected magnetic resonance. Our results pave the way for on-demand generation of SiV0 centers as well as other emerging quantum defects in diamond.
