论文摘要
将电子捕获到量子点中并控制其集体量子状态对于将半导体结构转换为量子信息处理的位至关重要。在这里，我们研究了在间隙双层石墨烯（BLG）中形成的量子点中的单个和两粒子状态，其中电子的山谷状态与它们的自旋量子数搭配出现，我们分析了各种BLG和DOT参数的自旋和山谷 - 和山谷 - 单词和三胞胎状态，以及两粒子的相互作用强度和外部磁场。
Trapping electrons in quantum dots and controlling their collective quantum states is crucial for converting semiconductor structures into bits of quantum information processing. Here, we study single- and two-particle states in quantum dots formed in gapped bilayer graphene (BLG), where the electron's valley states appear in pair with their spin quantum number and we analyse spin- and valley-singlet and triplet states for various BLG and dot parameters, as well as two-particle interaction strength and external magnetic field.
