Physics & Applications of Controlled Quantum Systems

这项研究计划探索在量子光学和纳米科学的界面上受控量子系统的基本物理和潜在的应用。这项工作涉及理论和实验之间的相互作用，并涉及两个广泛领域的潜在应用。第一个是单个自旋的传感和量子操纵，第二个是使用纳米光子系统的量子光学控制。具体地说，我们正在开发一种新的纳米级磁传感技术，该技术利用与钻石杂质相关的相干控制的单个电子自旋。此外，该系统还被用于与原子力显微镜(AFM)相关的磁化针尖的纳米机械运动的量子控制。更广泛的影响包括发展一个新的、跨学科的物理科学领域。我们正在提供对受控、复杂量子系统的基本物理的批判性见解。正在开发新的工具，利用相干量子现象进行独特的应用，从信息科学到生物和医学。我们的合作项目为这一新领域的教育和培训提供了绝佳的机会，该领域涉及基础物理、材料科学和设备工程等多个领域。我们通过教学、国际合作、复习文章、讲稿、工作坊和暑期班来传播物理知识。为加强对科学的欣赏和了解，将结合公众讲座和外展工作，例如参观小学。

This research program explores fundamental physics and potential applications of controlled quantum systems at the interface of quantum optics and nano-science. The work involves the interplay between theory and experiment and involves potential applications within two broad areas. The first is the sensing and quantum manipulation of individual spins, and the second is quantum optical control using nano-photonic systems. Specifically, we are developing a novel technique for nanoscale magnetic sensing that makes use of coherently controlled, individual electronic spins associated with diamond impurities. Furthermore, this system is being used for quantum control of nano-mechanical motion of the magnetized tip associated with an Atomic Force Microscope (AFM). The broader impacts include development of a new, interdisciplinary area of physical sciences. We are providing critical insights into the fundamental physics of controlled, complex quantum systems. New tools are being developed that make use of coherent quantum phenomena for unique applications ranging from information science to biology and medicine. Our collaborative program provides exceptional opportunities for education and training in this new area involving the interface of several fields of fundamental physics, material science, and device engineering. We disseminate physics knowledge through teaching, international collaborations, review articles, lecture notes, workshops and summer schools. To enhance the appreciation and understanding of science, public talks will be combined with outreach efforts, such as visits to elementary schools.
