Understanding, controlling, and harnessing increasingly complex many-body quantum systems is an important frontier of science, and is essential for the development of new materials and the advance of quantum information science. Elucidating how microscale physics determines the macroscale behavior of quantum systems is one of the grand, open questions of modern science and a physics frontier. The Center for Ultracold Atoms (CUA) is a joint effort between the Massachusetts Institute of Technology and Harvard University with the goal of creating, controlling, and studying intentional complexity in quantum systems. The CUA addresses this fundamental challenge in a collaborative and synergistic manner, using systems where the properties and interactions of particles at the microscopic scale are well understood, accurately quantified, and highly controllable at the quantum level. The CUA will also advance education and outreach with a broad portfolio of activities aimed at both the scientific community and the general public. The core outreach program, EngageCUA, extends participation in these activities to the whole CUA community.The CUA research activities are divided into four major areas. The first area focuses on quantum gases of atoms and molecules and aims at expanding control over many-body systems in multiple directions, including long-range forces and novel geometries (bilayer systems, frustrated lattices, gauge fields). The second area is programmable arrays of Rydberg atoms and molecules. They will be used to explore highly-entangled phases of matter, to perform fundamental research on error correction, and to pursue new applications, e.g., to quantum chemistry. The third area exploits atom-like and hybrid systems, including spin defects and trapped electrons and excitons in two-dimensional geometries. These solid-state systems will enable quantum simulations with strong interactions and new applications in sensing and metrology. The fourth area focuses on strongly coupled atoms and photons. The larger goal is to enable new capabilities for engineering many-body states of atoms and photons, with applications in quantum nonlinear optics, quantum metrology, and networking.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

理解，控制和利用日益复杂的多体量子系统是科学的重要边界，对于开发新材料和量子信息科学的发展至关重要。阐明微观物理学如何确定量子系统的宏观行为是现代科学和物理前沿的宏伟问题之一。 Ultracold Atoms（CUA）中心是马萨诸塞州技术学院和哈佛大学之间的共同努力，目的是创建，控制和研究量子系统中的故意复杂性。 CUA以协作和协同的方式解决了这一基本挑战，使用在微观尺度上颗粒的性质和相互作用的系统，可以很好地理解，准确量化且在量子水平上高度可控。 CUA还将通过针对科学界和公众的广泛活动来提高教育和宣传。核心外展计划Engagecua将这些活动的参与扩展到整个CUA社区。CUA研究活动分为四个主要领域。第一个区域的重点是原子和分子的量子气体，旨在扩大对多体系统的控制多个方向的控制，包括远距离力和新的几何形状（双层系统，沮丧的晶格，量规场）。第二个区域是Rydberg原子和分子的可编程阵列。它们将用于探索物质的高度进入阶段，进行误差纠正的基本研究，并追求新的应用，例如进行量子化学。 第三区域利用类似原子的和杂种系统，包括二维几何形状中的自旋缺陷以及捕获的电子和激子。这些固态系统将启用具有强烈相互作用和新应用的量子模拟。第四区域集中在强烈耦合的原子和光子上。更大的目标是启用用于工程多体原子和光子状态的新功能，并在量子非线性光学，量子计量和网络中应用。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来通过评估来支持的。
