The quantum world is very different from the classical, everyday, world. The mere act of measuring affects a quantum object so that applying feedback to control such object is rather delicate. The researchers will investigate quantum feedback on an experimentalapparatus, Cavity QED, which has been center to the development of quantum information science. The object of study is the spontaneously generated coherence observed in a cavity QED system with two polarization modes. We will look into ways to shield and protect the coherence from disturbances while applying feedback, while we will also develop post-selection protocols that help understand the disturbances affecting the system.One full time graduate student will be trained in the area of Atomic, Molecular, and Optical Physics with special focus on quantum optics. The student will have ample exposure to leaders in the field that visit the Joint Quantum Institute of the University of Maryland. There will be undergraduates participating in the research effort during the academic year, and in the summer. In conjunction with the Sociedad Mexicana de Física, two Mexican undergraduates will spend ten weeks in the laboratory. The results of the group will be available on the web page of the JQI as well as in the one of the group, with explanations for the general public. The students will give lab tours to prospective undergraduate students as well as to the undergraduates that take courses with the PI.

量子世界与每天的古典世界大不相同。仅测量的行为会影响一个量子对象，因此应用反馈来控制这种对象是相当微妙的。研究人员将调查有关实验性Apparatus腔QED的量子反馈，该Qed Qed一直是量子信息科学的发展。研究的对象是在具有两种极化模式的腔QED系统中观察到的赞助产生的相干性。我们将研究如何在应用反馈的同时屏蔽和保护连贯性免受灾难的侵害，同时我们还将开发出序列方案，以帮助了解影响系统的灾难。一名全职研究生将在原子，分子和光学物理学领域接受培训，并专注于量子光学。该学生将在访问马里兰大学联合量子研究所的领导人中充分接触。在学年和夏季，将会有本科生参加研究工作。与墨西哥墨西哥墨西哥社会的结合，两名墨西哥本科生将在实验室里呆十周。该小组的结果将在JQI的网页以及组之一上可用，并对公众提供了解释。学生们将向潜在的本科生以及与PI一起参加课程的本科生进行实验室旅行。
