Dissipation is generally a bad thing for quantum systems, robbing them of their special quantum features of coherence, superposition, and entanglement, and driving them to classical behavior. This project will endeavor to use dissipation in quantum systems for positive benefit. The research will develop techniques to use dissipation to remove unwanted energy, entropy, and randomness from a quantum system while preserving the wanted quantum information. A matter wave analogy to the field of quantum optics will be pursued, so that the important features that arise from interaction of matter with light can be replicated and perhaps expanded in a solely matter-based system.This research resides at the intersection of atomic physics, quantum information science, and condensed matter physics. Developing ways to engineer dissipation and understand and control open quantum systems will be relevant to virtually any new technological applications built on quantum mechanics, from a fully realized quantum computer to much more modest applications such as sensors based on coherent quantum mechanical processes. Graduate and undergraduate students will be trained in state-of-the-art science in an environment that exposes them to a wide variety of physics and research in both an academic and national lab setting.

耗散对量子系统来说通常是一件坏事，它剥夺了量子系统的相干、叠加和纠缠等特殊量子特性，并将它们推向经典行为。 这个项目将奋进在量子系统中使用耗散来获得积极的利益。 该研究将开发技术，利用耗散从量子系统中去除不需要的能量，熵和随机性，同时保留所需的量子信息。 将物质波类比为量子光学领域，这样，物质与光的相互作用所产生的重要特征可以在一个完全基于物质的系统中被复制和扩展。这项研究位于原子物理学，量子信息科学和凝聚态物理学的交叉点。开发设计耗散以及理解和控制开放量子系统的方法将与建立在量子力学基础上的几乎任何新技术应用相关，从完全实现的量子计算机到更温和的应用，如基于相干量子力学过程的传感器。研究生和本科生将在最先进的科学环境中接受培训，使他们在学术和国家实验室环境中接触各种各样的物理学和研究。
