论文摘要
近年来，基于半导体量子点的孔 - 旋转量子台以快速的速度提出。我们首先回顾了这些孔旋转量子量相对于它们的电子旋转对应物的主要潜在优势，并给出了描述它们的一般理论框架。讨论了价带中自旋 - 轨道耦合和超精细相互作用的基本特征，以及对相干和自旋操作的后果。在本文的第二部分中，我们提供了实验实现的调查，该调查涵盖了基于GAAS，SI或SI/GE ORSTRUCTURE的相对广泛的设备。我们以简短的前景结束。
In recent years, hole-spin qubits based on semiconductor quantum dots have advanced at a rapid pace. We first review the main potential advantages of these hole-spin qubits with respect to their electron-spin counterparts, and give a general theoretical framework describing them. The basic features of spin-orbit coupling and hyperfine interaction in the valence band are discussed, together with consequences on coherence and spin manipulation. In the second part of the article we provide a survey of experimental realizations, which spans a relatively broad spectrum of devices based on GaAs, Si, or Si/Ge heterostructures. We conclude with a brief outlook.
