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.

该项目的重点是使用量子理论来理解微观系统（电子自旋）和宏观系统（点环境、控制或测量）之间的相互作用。如asochasticity的概念产生的组合系统的演变，所示的测量结果的控制和实验观察的消相干和减少主动光学控制。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控制和光谱学，以及多体理论和光物质相互作用的合作者。
