The next quantum revolution will involve understanding and controlling the properties and dynamics of increasingly large-sized quantum systems. A better understanding of universal rules governing many-body quantum systems and deep understandings of more and more complex molecules will impact areas of science beyond quantum physics, including condensed matter and material physics, chemical and biophysics, high-energy physics, astrophysics, and nuclear physics. The Physics Frontiers Center (PFC) award to the JILA PFC will continue work begun during past PFC awards to harness interacting and interconnected atoms, molecules and photons to address frontier challenges presented by the complexity of quantum matter, and to probe elusive secrets of nature. The center program will also train a large number of graduate students and postdoctoral scholars with cutting-edge expertise in Atomic, Molecular, and Optical related physics, and it will develop tools and techniques to enhance the Nation's technological infrastructure. The JILA PFC will contribute to connecting scientific communities, by hosting workshops and schools and through the JILA visitor program. Continuing efforts to expand the undergraduate research program and a predominantly minority-serving after-school program will allow the JILA PFC to contribute to attracting the next generation of all students into science.The JILA PFC will capitalize on the development of extreme light sources and spectrographic techniques that have allowed the JILA PFC investigators to precisely engineer quantum states, probe complex interactions of atomic nuclei and electrons, and control matter in dynamic states far from equilibrium. The JILA PFC research is organized around four areas of research. The first two focus on aspects of many-body physics, including the construction of quantum matter from basic constituents and the development of quantum resources for precision measurements of physical systems including strongly interacting quantum many-body systems. The third area focuses on observations of coupled dynamics in different forms of matter, mainly solids and molecules, as well as the formation and transformation of constituents on unprecedented time scales, ranging from hundredths of a femtosecond to microseconds. The fourth area looks for opportunities to exchange ideas and technologies that could lead to projects outside of the central focus of the JILA PFC, but which would benefit either the core work of the PFC or other areas of science.

下一次量子革命将涉及理解和控制日益大型的量子系统的特性和动力学。 更好地理解控制多体量子系统的普遍规则以及对越来越复杂的分子的深入理解将影响量子物理学以外的科学领域，包括凝聚态和材料物理学、化学和生物物理学、高能物理学、天体物理学和核物理学。 物理前沿中心 (PFC) 授予 JILA PFC 的奖项将继续过去 PFC 奖项期间开始的工作，利用相互作用和互连的原子、分子和光子来解决量子物质的复杂性带来的前沿挑战，并探索难以捉摸的自然秘密。 该中心项目还将培养大量在原子、分子和光学相关物理学领域拥有尖端专业知识的研究生和博士后学者，并将开发工具和技术来增强国家的技术基础设施。 JILA PFC 将通过举办研讨会和学校以及 JILA 访客计划，为连接科学界做出贡献。持续努力扩大本科生研究项目和主要服务于少数族裔的课外项目将使 JILA PFC 能够为吸引下一代所有学生进入科学领域做出贡献。JILA PFC 将利用极端光源和光谱技术的发展，使 JILA PFC 研究人员能够精确设计量子态、探测原子核和电子的复杂相互作用以及控制物质 处于远离平衡的动态状态。 JILA PFC 研究围绕四个研究领域进行组织。 前两个重点关注多体物理学的各个方面，包括从基本成分构建量子物质以及开发用于物理系统（包括强相互作用的量子多体系统）精确测量的量子资源。 第三个领域侧重于观察不同形式的物质（主要是固体和分子）的耦合动力学，以及在前所未有的时间尺度（从百分之一飞秒到微秒）内成分的形成和转变。第四个领域寻找交流思想和技术的机会，这些思想和技术可能会导致 JILA PFC 的核心焦点之外的项目，但这将有利于 PFC 的核心工作或其他科学领域。
