论文摘要
硅中的受体掺杂原子最近被确定为基于自旋的量子技术的引人注目的候选者。对受体量子台的兴趣最终来自受体结合孔的性质，其中自旋轨道耦合量化了总角动量$ j = 3/2 $而不是旋转，而不是旋转，并赋予了四极耦合到电场和弹性场。单原子受体量子函数的这种特性使它们可以使用声子，电容性或微波光子光子介导的相互作用在长距离上进行电控制和耦合。本节被接受为量子技术的路线图中的贡献，回顾了单人体设备上的进度，观察同位素纯化硅中受体的超长连贯性时间，以及对单量子测量，长距离耦合的未来挑战的评论以及基于可伸缩的受体辅助机。
Acceptor dopant atoms in silicon have recently been identified as compelling candidates for spin-based quantum technologies. Interest in acceptor qubits ultimately derives from the properties of acceptor bound holes, where spin-orbit coupling quantizes total angular momentum $J=3/2$ rather than spin, endowing them with quadrupolar couplings to electric and elastic fields. This property of single-atom acceptor qubits makes them amenable to electric control and coupling over long distances using phonon, capacitive, or microwave photon mediated interactions. Accepted as a contribution within a roadmap for quantum technologies, this section reviews progress on single-acceptor devices, observation of ultra-long coherence times of acceptors in isotope purified silicon, and comments on future challenges in single qubit measurement, long distance coupling, and scalable acceptor-spin-based technologies.
