项目摘要

Nanoscale quantum optical systems enhance the efficacy of light-matter interactions by confining light in small regions. Such systems are integral to a myriad of emerging quantum technological applications: from building single-photon devices and storing and transmitting quantum information over long distances, to facilitating precision tests of fundamental physics. Thus, with growing efforts to miniaturize quantum systems, both with the fundamental motivation to explore quantum phenomena at nanoscales and also with the practical goal of developing modular on-chip architectures, atom-surface interactions at nanoscales become a central facet of developing novel quantum systems. However, when interfacing atoms at nanoscales from photonic structures, the ever-present quantum fluctuations of the electromagnetic field critically limit the ability to trap and control atoms. This work will develop ways to engineer such quantum fluctuation phenomena – forces, dissipation and decoherence – by leveraging the collective behavior of atomic systems and the ability to manipulate atoms with lasers. Overcoming these critical challenges in the design of nanoscale quantum systems will enable novel functionalities for quantum devices. In addition to the research goals, the PI will train a diverse undergraduate and graduate student workforce at the exciting intersection of Quantum Science and Engineering. As a part of the educational efforts, the PI will develop a multidisciplinary senior level course on Quantum Optics and Quantum Information, engaging students from a diverse array of Science and Engineering majors. This research will build a driven-dissipative Open Quantum Systems approach to engineering quantum fluctuation phenomena – Casimir-Polder forces, dissipation and decoherence – in collective atomic systems near surfaces with the goal to achieve better control and coherence of nanoscale quantum optical systems. The proposed program will build and advance new tools to control quantum fluctuation phenomena, with four main thrusts: (1) Realizing well-controlled and coherent atomic systems at distances of 10-100 nanometers from surfaces by developing near-surface trapping and cooling schemes; (2) Extending the framework of Casimir Physics and macroscopic QED to study fluctuation phenomena with objects that can be prepared in quantum superpositions, entangled or collective states and driven externally; (3) Guiding experiments on high-precision measurements of Casimir-Polder forces with atomic diffraction via nanogratings for creating repulsive drive induced Casimir-Polder forces and manipulating Casimir-Polder forces using collective effects; and (4) Mitigating fluctuation-induced decoherence in experiments with levitated dielectric nanospheres, to realize macroscopic quantum superpositions and correlated states of levitated nanoparticles.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.

纳米级量子光学系统通过限制小区域的光线来提高光 - 物质相互作用的效率。这样的系统是无数新兴量子技术应用不可或缺的一部分：从构建单光子设备，并在长距离内存储和传输量子信息到支持基本物理学的精确测试。这是越来越多地努力使量子系统的努力，既有探索纳米级量子现象的基本动机，又具有开发模块化片上体系结构的实际目标，纳米级的原子表面相互作用成为开发新型量子系统的核心方面。然而，当从光子结构中接口纳米级的原子时，电磁场的量子量不断限制限制捕获和控制原子的能力。这项工作将通过利用原子系统的集体行为以及用激光来操纵原子的能力来开发这种量子波动现象（力，耗散和反矫正）的方法。克服纳米级量子系统设计中的这些关键挑战将使量子设备的新功能具有新的功能。除了研究目标外，PI还将在量子科学与工程的令人兴奋的交汇处培训潜水员的本科生和研究生劳动力。作为教育工作的一部分，PI将开发有关量子光学和量子信息的多学科高级课程，使来自科学和工程专业的潜水员阵列的学生吸引学生。这项研究将在集体原子系统靠近表面的集体原子系统中建立驱动驱动性开放量子系统方法，用于工程量子波动现象 - Casimir-Polder力量，耗散和腐蚀性 - 旨在实现纳米级量子光学系统的更好控制和相干性。提出的程序将构建和推进新的工具，以控制量子波动现象，并具有四个主要推力：（1）通过开发近乎面膜的捕获和冷却方案来实现与表面10-100纳米范围内的良好控制和相干的原子系统；（2）扩展Casimir物理学和宏观Q的框架，以研究可以在量子叠加，纠缠或集体状态并在外部驱动的物体中研究波动现象；（3）指导实验对Casimir-polder力量的高精度测量，其原子衍射是通过纳米衍射来产生排斥驱动引起的Casimir-Polder力并使用集体效应来操纵Casimir-Polder力的实验；（4）在悬浮的饮食纳米球实验中减轻波动诱导的解谐，以实现悬浮的量子叠加和悬浮纳米颗粒的相关状态。这项奖项反映了NSF的法定任务，并通过评估智力的智力效果来诚实地对其进行评估。
