The ability to create and control large-scale, coherent quantum many-body systems has wide-ranging implications for both technology and progress in fundamental sciences. It enables the generation and manipulation of entanglement, which forms the experimental foundation for quantum computers. It is necessary for quantum simulation, where highly-controlled experimental implementations shed light on outstanding questions in condensed matter physics, quantum chemistry, or high-energy physics. And it is an important building-block for realizing quantum-enhanced metrology schemes at the heart of future atomic clocks and sensor devices. Here, this project will implement such highly-controlled, large-scale quantum many-body systems with arrays of ultracold, alkaline-earth strontium atoms that are assembled and manipulated in an atom-by-atom fashion with optical tweezers and controlled via ultra-precise clock state manipulation. This platform has immediate usability in all three major directions of quantum science: quantum computing, quantum simulation and quantum-enhanced metrology. The broader impact of this research stems from the transformative effect that quantum technologies can have on society. Yet, quantum physics is not a part of basic education. Therefore, a primary goal of the educational and outreach program is to make quantum physics more accessible for a broader audience.This research program directly addresses the 'experimental quantum many-body challenge' by combining elements of quantum gas microscopes, atom-by-atom assembly, and optical lattice clocks into a novel experimental platform with unique capabilities. This combination of features will enable a host of new developments, including novel atomic clocks based on single-atom control, quantum-enhanced metrology and quantum simulation schemes based on Rydberg interactions, or the bottom-up assembly of Hubbard and orbital-exchange models. Finally, this platform can realistically reach defect-free arrays of hundreds of atoms by implementing scalable atom-by-atom assembly. The aim is to combine large system sizes, precision control over individual particles, and coherent control over interaction mechanisms.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.

创造和控制大规模相干量子多体系统的能力对基础科学的技术和进步都有广泛的影响。它能够产生和操纵纠缠，这构成了量子计算机的实验基础。它对于量子模拟是必要的，在量子模拟中，高度受控的实验实现揭示了凝聚态物理，量子化学或高能物理中的突出问题。它是实现未来原子钟和传感器设备核心的量子增强计量方案的重要组成部分。在这里，该项目将实现这种高度受控的大规模量子多体系统，这些系统具有超冷碱土锶原子阵列，这些原子阵列通过光镊以原子接原子的方式组装和操纵，并通过超精确的时钟状态操纵进行控制。该平台在量子科学的所有三个主要方向都具有即时可用性：量子计算，量子模拟和量子增强计量学。这项研究的更广泛影响源于量子技术对社会的变革性影响。然而，量子物理学并不是基础教育的一部分。因此，教育和推广计划的一个主要目标是使量子物理学更容易为更广泛的受众所接受。该研究计划通过将量子气体显微镜、原子对原子组装和光学晶格钟的元素结合到一个具有独特功能的新颖实验平台中，直接解决“实验量子多体挑战”。这种功能的组合将实现一系列新的发展，包括基于单原子控制的新型原子钟，量子增强计量学和基于里德伯相互作用的量子模拟方案，或自下而上的哈伯德和轨道交换模型组装。最后，该平台可以通过实现可扩展的原子-原子组装来实现数百个原子的无缺陷阵列。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
