This research program aims to demonstrate high-efficiency storage and retrieval of light pulses while preserving the quantum state of the photons. Such quantum memory for photons can be realized by mapping the quantum states of light to the collective excitation of spins inside an ensemble of identical atoms using a dynamic form of electromagnetically induced transparency. Some essential elements of practical quantum information "toolbox" will be developed, including universal quantum memory optimization techniques, low-loss/high-rejection optical filters, and sources of single photon pulses and continuous light with non-classical statistics ("squeezed light" or "squeezed vacuum") based on both nonlinear atomic media and high-quality crystalline microresonators. These experiments will have significant educational and scientific broader impacts. Most of the experimental results are applicable for wide variety of atomic, solid-state and photonic systems, and an ensemble of warm rubidium atoms will serve as a prototype interaction medium, and they will advance practical realization of quantum information technologies, such as quantum repeaters. The other broader impact of the program is involvement of undergraduate and graduate students at different levels in cutting-edge scientific research, and educating them about basic concepts of atomic physics, quantum optics and quantum information science.

该研究计划旨在展示光脉冲的高效存储和检索，同时保持光子的量子态。光子的这种量子存储可以通过使用电磁诱导透明的动态形式将光的量子态映射到相同原子系综内的自旋的集体激发来实现。将开发实用量子信息“工具箱”的一些基本要素，包括通用量子存储器优化技术、低损耗/高抑制光学滤波器以及基于非线性原子介质和高质量晶体微谐振器的具有非经典统计的单光子脉冲和连续光（“压缩光”或“压缩真空”）源。这些实验将产生重大的教育和科学影响。大多数实验结果适用于各种原子，固态和光子系统，热铷原子系综将作为原型相互作用介质，它们将推动量子信息技术的实际实现，如量子中继器。该计划的另一个更广泛的影响是不同层次的本科生和研究生参与尖端科学研究，并教育他们原子物理学，量子光学和量子信息科学的基本概念。
