Spin qubits in optically-active lattice-matched quantum dots

量子点，被称为人造原子，是纳米尺寸的半导体晶体，其中单个电荷的状态根据量子力学定律表现。量子点电子的量子化磁态在量子信息存储和处理中得到了广泛的研究。量子科学和半导体纳米技术的最新进展导致了新型量子点的发展。在这些晶格匹配的纳米结构中，不仅可以对电荷而且可以对原子核实现磁状态的量子控制。该项目的目的是开发适用于多体核自旋系综以及嵌入量子点晶格的单个原子状态的量子控制技术。这项工作将提供对纳米尺度量子物理的深入理解，并为新一代具有大规模片上集成的固态量子信息处理设备创建平台。

Quantum dots, known as artificial atoms, are nanometer-sized semiconductor crystals where the states of individual charges behave according to the laws of quantum mechanics. The quantized magnetic states of the quantum dot electrons have been widely studied for the purpose of quantum information storage and processing. Recent advances in quantum science and semiconductor nanotechnology resulted in development of a new type of quantum dots. In these lattice-matched nanostructures quantum control of magnetic states can be achieved not only for charges but also for the atomic nuclei. The aim of this project is to develop quantum control techniques applicable to many-body nuclear spin ensembles as well as the states of individual atoms embedded of the quantum dot crystal lattice. This work will provide in-depth understanding of the nanoscale quantum physics and create a platform for a new generation of solid-state quantum information processing devices with large-scale on-chip integration.
