Quantum Optics with Narrow Band Entangled Photon States

本课题主要研究窄带双光子纠缠态光的量子干涉和纠缠。本研究项目的主要目标是：(1)在简并模式和非简并模式下，开发可靠、稳定的窄带双光子态源；(2)在涉及独立光源之间量子干涉的若干实验中使用新光源；(3)通过腔QED探索纠缠源与原子跃迁的直接相互作用或强相互作用。这项工作的更广泛的影响将是开发有用的工具，并培养量子信息科学和工程的年轻科学家。

This research program focuses on the study of quantum interference and entanglement using a narrow band entangled two-photon state of light. The major objectives of the research program are: (1) to develop a reliable and stable source of narrow band two-photon state in both degenerate and non-degenerate modes; (2) to employ the new source in a number of experiments involving quantum interference between independent sources; (3) to explore the direct interaction of the entangled source with atomic transitions or strong interaction through cavity QED. The broader impact of this work will be to develop useful tools and to train young scientists for quantum information science and engineering.
