项目摘要

NONTECHNICAL SUMMARYThis CAREER award will support research and education aimed at developing new theoretical techniques and high-performance computer software that enable the exploration and measurement of quantum properties of interacting quantum gases and liquids of atoms at low temperatures. The laws of quantum mechanics are fundamentally responsible for limiting the speed and efficiency of current computers by imposing a minimum physical size for their logical components. However, the same laws can be exploited to bring about exponentially faster computation and secure communication by harnessing quantum entanglement as a resource for information processing applications. Entanglement is a purely quantum property of a system that has no analog in our everyday experience. It reflects connections between the properties of a quantum system's parts, even after the parts become physically separated. For example, a measurement of a specific property on one part will instantly determine the outcome of a measurement of the same property on a physically separate part. The PI will investigate the feasibility of using quantum systems that can be easily produced in modern laboratories as sources of entanglement that can be exploited for future quantum technologies. All software developed as part of this project will be made available to the community on public repositories.In tandem with the research projects, the PI will drive increased enrollment in post-secondary science programs at the University of Vermont by engaging with a diverse group of high-school students, with a focus on students from low-income families. The PI will participate in the Upward Bound college preparation program, and provide pedagogical lectures, science career counseling, and summer research internship opportunities to local high schools. To address the fact that Vermont is the only state in the country not offering a Ph.D. degree in physics, this award will allow the PI to design graduate courses on quantum computing, and spearhead a grassroots strategic planning committee to advance the development of graduate physics programs in the state.TECHNICAL SUMMARYThis CAREER award supports research and education aimed at developing high-performance computer simulation tools that will be used to determine the amount of entanglement that can be extracted from strongly interacting quantum liquids and gases. By quantifying this quintessentially nonclassical correlation property in experimentally accessible phases of quantum many-body systems, their feasibility and potential as an entanglement resource for quantum information processing protocols will be evaluated. In this project, the PI will focus on: i) providing quantitative comparisons with nascent experimental measurements of the entanglement entropy across the Mott insulator to superfluid transition of ultracold atoms in optical lattices, aiding in the design of future searches, ii) discovering the amount of operational entanglement in superfluid helium-4, a tabletop macroscopic quantum phase, iii) exploring entanglement scaling in systems with long-range interactions and deformed spatial boundaries, which have implications for the discovery of universal, and potentially transformative, emergent physical phenomena. The quantum Monte Carlo algorithms and open-source software developed during this CAREER project will allow for the measurement and optimization of quantum entanglement in a large class of ab initio Hamiltonians describing interacting particles in the spatial continuum. These capabilities may contribute to accelerating the design and construction of next-generation quantum technologies.

非技术摘要该职业奖将支持旨在开发新理论技术和高性能计算机软件的研究和教育，这些技术和软件能够探索和测量低温下原子相互作用的量子气体和液体的量子特性。量子力学定律从根本上限制了当前计算机的速度和效率，因为它规定了逻辑组件的最小物理尺寸。然而，通过利用量子纠缠作为信息处理应用的资源，可以利用相同的定律来实现指数级更快的计算和安全通信。纠缠是系统的纯粹量子特性，在我们的日常经验中没有类似物。它反映了量子系统各部分的属性之间的联系，即使这些部分在物理上是分离的。例如，对一个零件上的特定属性的测量将立即确定对物理上独立的零件上的相同属性的测量结果。 PI 将研究使用可在现代实验室轻松生产的量子系统作为可用于未来量子技术的纠缠源的可行性。作为该项目一部分开发的所有软件都将在公共存储库上向社区提供。在开展研究项目的同时，PI 将通过与多元化的群体合作，推动佛蒙特大学高等教育科学项目的入学人数增加。高中生，重点是低收入家庭的学生。 PI将参加Upward Bound大学预科项目，并向当地高中提供教学讲座、科学职业咨询和暑期研究实习机会。为了解决佛蒙特州是美国唯一一个不提供博士学位的州的事实。获得物理学博士学位后，该奖项将允许 PI 设计量子计算研究生课程，并领导一个基层战略规划委员会，推动该州研究生物理学项目的发展。技术摘要该职业奖支持旨在发展高科技的研究和教育。高性能计算机模拟工具将用于确定可以从强相互作用的量子液体和气体中提取的纠缠量。通过在量子多体系统的实验可访问阶段中量化这种典型的非经典相关性，将评估它们作为量子信息处理协议的纠缠资源的可行性和潜力。在这个项目中，PI将重点关注：i）提供与莫特绝缘体到光学晶格中超冷原子的超流体跃迁的纠缠熵的新生实验测量的定量比较，帮助设计未来的搜索，ii）发现数量超流氦 4（一种桌面宏观量子相）中的操作纠缠，iii) 探索具有长程相互作用和变形空间边界的系统中的纠缠尺度，其中对于发现普遍的、潜在的变革性的自然现象具有重要意义。在这个 CAREER 项目期间开发的量子蒙特卡罗算法和开源软件将允许测量和优化一大类描述空间连续体中相互作用粒子的从头算哈密顿量中的量子纠缠。这些能力可能有助于加速下一代量子技术的设计和构建。作为该项目一部分开发的所有软件都将在公共存储库上向社区提供。在开展研究项目的同时，PI 将通过与多元化的群体合作，推动佛蒙特大学高等教育科学项目的入学人数增加。高中生，重点是低收入家庭的学生。 PI将参加Upward Bound大学预科项目，并向当地高中提供教学讲座、科学职业咨询和暑期研究实习机会。为了解决佛蒙特州是美国唯一一个不提供博士学位的州的事实。获得物理学博士学位后，该奖项将允许 PI 设计量子计算研究生课程，并带头组建一个基层战略规划委员会，以推动该州研究生物理学项目的发展。
