论文摘要
使用最近开发的量子嵌入理论，我们提出了钻石中旋转缺陷密切相关状态的第一原理计算。在该理论中，建立了有效的哈密顿素化学，可以通过经典和量子计算机来解决。后者有望比前者更有利的缩放缩放量比系统大小。特别是，我们报告了一项对钻石中中性IV的空位复合物的研究，并讨论了它们强相关的旋转单词和自旋三键激发态。我们的结果为旨在光学操纵这些缺陷的量子信息技术应用的实验提供了宝贵的预测。
Using a recently developed quantum embedding theory, we present first principles calculations of strongly correlated states of spin defects in diamond. Within this theory, effective Hamiltonians are constructed, which can be solved by classical and quantum computers; the latter promise a much more favorable scaling as a function of system size than the former. In particular, we report a study of the neutral group-IV vacancy complexes in diamond, and we discuss their strongly-correlated spin-singlet and spin-triplet excited states. Our results provide valuable predictions for experiments aimed at optical manipulation of these defects for quantum information technology applications.
