Acquisition of Instrumentation for Multidisciplinary Experimental and Theoretical Research in Quantum Information and Quantum Control

该MRI奖为购买高性能集群计算机进行建模提供资金；用于100皮秒激光系统的高重复频率激光放大器两个光学参数放大器，用于产生可调谐的超短（40飞秒脉冲与30飞秒激光系统相关联）；以及用于诊断短脉冲的频率分辨光门控装置。该设备的研究目标将涵盖(1)量子测量、控制、纠缠和信息，(2)光学、半导体和等离子波导器件的相干动力学，以及(3)复杂系统。这些设备将被安置在一个新的联合使用实验室中，预计将促进正在进行和未来的合作。量子信息与控制是一个广泛的跨学科领域，涉及物理、化学和工程，解决小量子系统的控制操作和状态测量，包括原子、分子、半导体结构、金属纳米膜和光子。在量子控制研究中取得进展的一个关键方面是能够从理论上模拟复杂的量子动力学。大规模并行（集群）计算机体系结构应该使涉及相干动力学和量子随机行为的问题的解决成为可能，这些问题要么是系统动力学的固有部分，要么是量子测量期间状态坍缩的必然结果。该项目的广泛影响是双重的。在科学和技术领域，许多研究对未来的量子信息技术有直接的影响。这些包括提高计算机能力和新型电子、光学和通信设备。最终，在量子水平上运行的信息处理设备可能会导致我们对物理过程的理解的革命，以及我们解决目前无法解决的计算问题的能力。此外，还将出现100ps脉冲整形设备等衍生技术，这将立即影响电信和激光光谱学等其他领域。这将直接影响到大学的教育使命。激光器和集群系统将被博士后研究助理以及与参与者的研究项目相关的博士、硕士、学士和高中生使用。这将是俄勒冈州唯一的同类实验室，并将为该地区的学生提供更多的机会。拟议研究的跨学科合作将大大增加学生和博士后培训的广度和质量。

This MRI award provides funds to purchase a high-performance cluster computer for modeling; a high repetition-rate laser amplifier for a 100 picosecond laser system; two optical parametric amplifiers for generating tunable ultrashort (40 femtosecond pulses in association with a 30 femtosecond laser system); and frequency resolved optical gating apparatus for diagnostics of short pulses. The research goals that this equipment will enable cover the topics of (1) Quantum measurement, control, entanglement and information, (2) Coherent dynamics of optical, semiconductor, and plasmonic waveguide devices, and (3) Complex systems. The equipment will be housed in a new joint-use laboratory, where it is expected to facilitate ongoing and future collaborations. Quantum information and control comprises a broad interdisciplinary field involving physics, chemistry, and engineering that addresses the controlled manipulation and state measurement of small quantum systems including atoms, molecules, semiconductor structures, metal nanofilms, and photons. A critical aspect for making progress in quantum-control research is the ability to model theoretically complex quantum dynamics. A massively parallel (cluster) computer architecture should make possible the solution of problems involving coherent dynamics and quantum stochastic behavior, which arise either as an intrinsic part of a system's dynamics or as a necessary consequence of state collapse during quantum measurements. The broader impact of the project is twofold. In the scientific and technological arena, much of the research has direct implications for future quantum-information technologies. These include increased computer capability and new types of electronic, optical, and communication devices. Ultimately, information-processing devices operating at the quantum level may lead to a revolution of our understanding of physical processes as well as our ability to solve computational problems that are now inaccessible. In addition, there will be spin-off technologies such as the 100ps pulse-shaping devices, which will immediately impact other areas such as telecommunication and laser spectroscopy. There will be a direct impact on the educational mission of the university. Both the lasers and cluster system will be used by postdoctoral research associates, as well as Ph.D., masters, bachelors, and high-school students associated with the research programs of the participants. This will be the only laboratory of its kind in Oregon, and will provide expanded opportunities for students in the region. The interdisciplinary collaborations of the proposed research will add greatly to the breadth and quality of the student and postdoc training.
