Information processing (IP) is at the heart of the modern economy. The cutting edge of IP is a new paradigm -- "quantum information processing," (QIP) -- where bits are encoded in microscopic states of light and matter. The nonintuitive properties of quantum mechanics such as superposition and entanglement allow for computations, communications, and measurements beyond the power and any existing IP device. This grant studies the implementation of QIP with atomic gasses cooled to ultralow temperatures. Laser beams act as a quantum databus to entangle atoms with one another, and as a mechanism for reading out the information. The control of atoms is studied to create new quantum states that have the unique properties necessary for QIP. This work is theoretical, carried out in close collaboration with laboratory experiments. The research contributes to the knowledge base of quantum information science, and to the training of future scientists in this highly interdisciplinary field. Students will be involved in all aspects of the project, including education, research, and the dissemination of results. The project is an integral part of the NSF-funded Center for Quantum Information and Control (CQuIC). We use video conferencing to allow participation of CQuIC partners in the regular activities of CQuIC, including weekly group meetings and research seminars, and strengthen the connections between junior and senior members through an annual research retreat. All students and senior personnel actively participate in the Southwest Quantum Information Technology (SQuInT) network, including the annual workshop. During its 15-year history SQuInT has provided a vibrant avenue for exchange of ideas and results in QIS, with particular emphasis given to PhD students, postdocs, and new researchers in the field.

信息处理（IP）是现代经济的核心。 IP的尖端是一种新的范式 - “量子信息处理”（QIP），其中位在光和物质的微观状态下编码。 量子力学（例如叠加和纠缠）的非直觉特性允许超出电源和任何现有IP设备以外的计算，通信和测量。 该赠款研究了QIP的实施，其原子气体被冷却至超低温度。 激光束充当量子数据库，可以彼此纠缠原子，也是读取信息的机制。 研究了原子的控制，以创建具有QIP所需的独特属性的新量子状态。 这项工作是理论上的，与实验室实验密切合作进行。 该研究为量子信息科学的知识基础以及在这个高度跨学科领域的未来科学家的培训做出了贡献。学生将参与该项目的各个方面，包括教育，研究和结果传播。该项目是NSF资助的量子信息和控制中心（CQUIC）的组成部分。我们使用视频会议来允许CQUIC合作伙伴参加CQUIC的常规活动，包括每周的小组会议和研究研讨会，并通过年度研究务虚会加强初级与高级成员之间的联系。所有学生和高级人员都积极参与西南量子信息技术（sindint）网络，包括年度研讨会。在15年的历史中，斜视为QIS的思想和结果提供了充满活力的途径，特别强调了该领域的博士生，博士后和新研究人员。
