论文摘要
文学中已经证明了$^{29} $ siv $^{ - } $中心的电子旋转的相干控制和光学读数，在文献中已经证明了这一点，作为内存节点和旋转量子的实现前景。核自旋可能更适合许多量子信息处理，因为它们的连贯性很长。控制$^{29} $ siv $^{ - } $使用常规NMR技术的核旋转是可行的，尽管由于核旋转的低旋转磁比，但以缓慢的kilohertz速率以缓慢的速率。在这项工作中，我们从理论上说明了如何使用电子自旋轨道效应的间接控制来进行高速，对$^{29} $ SI核自旋的高速控制。我们讨论核自旋进动频率对栅极时间的影响以及所有光学核自旋控制的令人兴奋的可能性。
Coherent control and optical readout of the electron spin of the $^{29}$SiV$^{-}$ center in diamond has been demonstrated in literature, with exciting prospects for implementations as memory nodes and spin qubits. Nuclear spins may be even better suited for many applications in quantum information processing due to their long coherence times. Control of the $^{29}$SiV$^{-}$ nuclear spin using conventional NMR techniques is feasible, albeit at slow kilohertz rates due to the nuclear spin's low gyromagnetic ratio. In this work we theoretically demonstrate how indirect control using the electron spin-orbit effect can be employed for high-speed, megahertz control of the $^{29}$Si nuclear spin. We discuss the impact of the nuclear spin precession frequency on gate times and the exciting possibility of all optical nuclear spin control.
