The quantum optics group at the University of Maryland is investigating entanglement between atoms and light. The experiments study the dynamics of entanglement in a system that consists of an atom interacting with light inside an optical cavity; the so called cavity quantum electrodynamics (cavity QED) system. To protect the entanglement, quantum feedback will be implemented. The quantification of entanglement and the control of non-classical states will help elucidate the fragility of this fundamental resource necessary in the development of quantum information protocols. This project involves three graduate students in the area of Atomic, Molecular, and Optical Physics. The students will be part of the Joint Quantum Institute that brings to the University of Maryland internationally recognized scientist interested in the topics of quantum information and quantum coherence. The experiment involves undergraduates participating in the research effort during the academic year, and in the summer. In conjunction with the Sociedad Mexicana de Fisica, two Mexican undergraduates will spend two months in the laboratory.

马里兰大学的量子光学小组正在研究原子和光之间的纠缠。实验研究了由原子与光在光学腔内相互作用组成的系统中的纠缠动力学；即所谓的腔量子电动力学（腔QED）系统。为了保护纠缠，量子反馈将被实现。纠缠的量化和对非经典状态的控制将有助于阐明量子信息协议发展中所必需的这种基本资源的脆弱性。该项目涉及原子、分子和光学物理领域的三名研究生。这些学生将成为联合量子研究所的一部分，该研究所将为马里兰大学带来对量子信息和量子相干感兴趣的国际知名科学家。该实验要求本科生在学年和夏季期间参与研究工作。两名墨西哥本科生将与墨西哥社会科学协会（Sociedad Mexicana de Fisica）合作，在实验室呆上两个月。
