The general theme of this project is to investigate methods to create, distribute, and store quantum mechanical states by exploring entanglement between light and matter with ensembles of ultracold atoms. Entanglement, one of the most striking features of quantum mechanics, leads to strong correlations between separate components of a physical system, regardless of the distance separating them. The first specific goal of the project is to develop methods of creating robust entanglement between light and matter with ensembles of ultracold atoms. This project builds upon previously realized entanglement of mixed species atomic "quantum bits" (called qubits) and frequency-encoded photonic qubits. The approach avoids the use of two interferometrically separate paths for qubit entanglement distribution. The second goal is to realize matter-light entanglement at telecommunications wavelengths as an enabling technology to distribute and store entanglement over long distances. The final component of the program involves investigations of dynamics of the entangled systems subjected to continuous measurement.Achieving these goals should significantly develop atomic physics-based methods for the processing of quantum information. The program involves extensive undergraduate and graduate student training and participation in technologically important areas of physics. The project will include outreach to the Atlanta community through laboratory tours and summer workshops for local high-school teachers.

该项目的总主题是通过探索光与超冷原子系综之间的纠缠来研究创建，分配和存储量子力学状态的方法。纠缠是量子力学最显著的特征之一，它导致了物理系统中各个组成部分之间的强相关性，而不管它们之间的距离如何。 该项目的第一个具体目标是开发在光和物质之间产生强大纠缠的方法，并使用超冷原子的合奏。 该项目建立在先前实现的混合物种原子“量子比特”（称为量子比特）和频率编码光子量子比特的纠缠基础上。 该方法避免了使用两个干涉分离的路径进行量子比特纠缠分发。 第二个目标是在电信波长上实现物质-光纠缠，作为一种使能技术，在长距离上分发和存储纠缠。 该计划的最后一个组成部分是研究连续测量的纠缠系统的动力学。实现这些目标将大大发展基于原子物理的量子信息处理方法。该计划涉及广泛的本科生和研究生培训和参与物理学的重要技术领域。 该项目将包括通过实验室图尔斯参观和为当地高中教师举办暑期讲习班，向亚特兰大社区进行宣传。
