Coherent Optical Manipulation and Spectroscopy of Semiconductor Quantum Dots Spins at the Single Dot Level

该项目的重点是利用量子理论提供对微观系统（电子自旋）和宏观系统（物理环境、控制或测量）之间相互作用的理解。如控制的测量结果和退相干的实验观察以及主动光学控制对退相干的减少所证明的那样，诸如随机性之类的概念是从组合系统的演化中产生的。这项研究处于应用量子物理学的前沿。它涉及半导体纳米结构物理学，量子点的高精度相干光学控制和光谱学，以及多体理论和光物质相互作用的合作者。

The project focuses on providing an understanding of the interaction between amicroscopic system (the electron spins) and a macroscopic system (the dotenvironment, control or measurement) using quantum theory. Concepts such asstochasticity arise out of the evolution of the combined system, as demonstrated by measured results of control and by experimental observation of decoherence and its reduction by active optical control. The research is at the frontier of applied quantum physics. It involves collaborators in the physics of semiconductor nanostructures, in high-precision coherent optical control and spectroscopy of quantum dots, and in many-body theory and light-matter interaction.
