This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). The requirement of establishing a strong coupling between light (quantized electromagnetic radiation) and single atoms (quantum emitters) is ubiquitous in the fundamental studies of light-matter interaction at the smallest scale. Typically, this interaction is simplified to a scenario of single-mode fields trapped inside optical cavities and coupled with a single atom. However, the recent advancements in quantum computing and quantum networking are requiring the coherent control of 100-1000 quantum bits (qubits) with the possibility of reliable quantum communication over 100s kilometers. In this context, multiple-emitter waveguide quantum electrodynamics (one-dimensional waveguides/fibers strongly coupled with a chain of atoms) has emerged as a fascinating platform due to its ability to host several useful quantum effects (such as quantum correlations e.g., entanglement, atom-photon bound state formation, one-way light-matter interaction or chirality, controlled photon transport, and collective photon emission, etc.) in a single setup. This project aims to study one-way or chiral waveguide quantum electrodynamics architectures as a testbed to investigate many-body quantum optical effects under the influence of environmental interactions. The completion of this project will result in the development of more powerful theoretical and numerical tools that will go beyond the typical single-atom single-mode field interaction paradigm of quantum optics and will be suitable for the examination of the state-of-the-art and futuristic quantum technological devices. The project includes the development of a two-year program of integrating research and education in quantum optics and quantum information science (QIS) in the Physics Department at Miami University. With the growing interest and investment in the National Quantum Initiative, there is a demand for training the next generation of workforce in QIS. This award will offer such training opportunities by engaging historically underrepresented students through direct outreach at the high school and undergraduate levels. To further extend the outreach program, the PI will develop online and face-to-face modules accessible to high school students through the Miami University Summer Scholar Program and undergrad students through the Miami University eLearning department. In particular, the proposed research here aims to: (1) perform an in-depth theoretical study of the quantum transport properties of few (one, two, or three)-photon Fock states in chiral waveguides that are simultaneously coupled with several noisy quantum emitters, and to (2) analyze the generation and control of several types of quantum effects such as entanglement between emitters, collective emitter effects (superradiance, subradiance, selective radiance), and emitter-cavity bound states, etc. Open quantum system approaches (Markovian and non-Markovian master equations, real-space quantization technique, and quantum jump approach) will be utilized to quantify the photon transport in terms of reflection and transmission spectra, second-order correlation functions as well as to predict the time evolution of emitter- waveguide systems. At every stage of the project, the connection of the results obtained with the experimentally feasible applications in quantum information transfer, storage, and processing protocols will also be emphasized. Additionally, while accomplishing the goals of the project, the PI will train a group of two graduate and six undergraduate students in quantum information science at Miami University. The PI will also introduce concepts of quantum computation in various undergraduate-level physics courses and will offer quantum computing modules for underrepresented groups of high school students through the Miami University Summer Scholar Program.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.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。 在最小尺度上光 - 摩尔物相互作用的基本研究中，在光（量化电磁辐射）和单个原子（量子发射器）之间建立强耦合的要求是无处不在的。通常，将这种相互作用简化为被困在光腔内的单模字段的场景，并与单个原子结合。但是，量子计算和量子网络的最新进展是需要对100-1000个量子位（Qubits）的连贯控制，并可能在100s公里以上可靠的量子通信。 In this context, multiple-emitter waveguide quantum electrodynamics (one-dimensional waveguides/fibers strongly coupled with a chain of atoms) has emerged as a fascinating platform due to its ability to host several useful quantum effects (such as quantum correlations e.g., entanglement, atom-photon bound state formation, one-way light-matter interaction or chirality, controlled photon transport, and collective photon emission,等）在一个设置中。该项目旨在研究单向或手性波导量子电动力学体系结构作为测试床，以研究环境相互作用的影响多体量子光学效应。该项目的完成将导致更强大的理论和数值工具的开发，这些工具将超出量子光学元件的典型单原子单模现场相互作用范式，并且适合检查先进和未来式的量子技术设备。该项目包括开发一项为期两年的计划，该计划在迈阿密大学物理系中整合量子光学和量子信息科学（QIS）的研究和教育。随着国家量子倡议的兴趣和投资的日益增长，需要培训QIS的下一代劳动力。该奖项将通过在高中和本科级别的直接推广中吸引历史不足的学生来提供此类培训机会。为了进一步扩展外展计划，PI将通过迈阿密大学夏季学者计划和本科生通过迈阿密大学电子学习系开发在线和面对面的模块。特别是，此处提出的研究旨在：（1）对量子传输属性进行深入的理论研究，对手性波导中的量子传输属性（一，一个，两个或三个）fock态同时与几种噪声量子发射器同时耦合，并分析（2）分析EMITENS EMITERS EMITERS EMITERS EMITERS EMITERSERIANS EMITERSERISER EMITERS的产生，以及（2）将利用开放的量子系统方法（马尔可夫和非马克维亚主方程，真实空间量化技术和量子跳跃方法）来量化光子传输，以反射和二阶相关功能来量化光子传输，以预测emitter-time-time-time-time-time-time-time-time-time wave drougn emprave，在项目的每个阶段，还将强调使用实验可行的应用在量子信息传输，存储和处理协议中获得的结果的连接。此外，在实现该项目的目标的同时，PI将在迈阿密大学培训一组两名毕业生和六名本科生。 PI还将通过迈阿密大学夏季学者计划为各种本科生的物理课程介绍量子计算的概念，并将为代表性不足的高中生提供量子计算模块。这一奖项反映了NSF的法规任务，并认为通过基金会的知识优点和广泛的criter criter crietia criter crietia criter criter criter criter criter criteria criteria crietia criter criteria criteria crietia crietia crietia crietia crietia cripitia均值得通过评估。
