项目摘要

Abstract (Raymer 0621723)The objective of this research is to develop solid-state sources of single photons and the means to interact such photons coherently with an active center in a solid. Quantum information technology will be enabled by creating photons on demand in a deterministic manner. Applications include improved quantum key distribution, long-distance transmission of quantum entanglement, distributed processing, quantum error correction, and qubit repeaters. The experimental approach is to use a high-finesse hemispherical optical micro-cavity to enhance the interactions of photons with semiconductor quantum dots and with optical centers in diamond nanocrystals. Modeling for quantum dynamics will be developed in support. Intellectual Merit The engineering of photon sources requires tailoring the interaction between the optical field and the atomic emitters. This requires an integrated understanding of classical and quantum field theory, and solid-state physics. By proper cavity design, the coherent interaction between the cavity mode and a single emitter can be made to dominate the decay mechanisms that usually lead to incoherent emission. Such strong coupling will allow coherent exchange of energy between cavity and emitter, which is at the heart of quantum information processing. Broader impacts include potential breakthroughs in communications and information processing. Quantum information technology is attracting students into research, including graduate, undergraduate and REU. In the Oregon Center for Optics, students participate in teaching laboratories, seminars, joint group meetings, outside collaborators, and annual research retreats. The PI recently initiated a course for undergraduate non-science majors, called The Physics Behind the Internet, on the physical basis for information technology. A companion textbook is scheduled for publication in 2007.
摘要(Raymer 0621723)本研究的目的是开发单光子的固态源,以及使这些光子与固体中的活性中心相干地相互作用的方法。量子信息技术将通过以确定性的方式按需创建光子来实现。应用包括改进的量子密钥分配,量子纠缠的长距离传输,分布式处理,量子纠错和量子比特中继器。实验方法是使用高精细度的半球形光学微腔来增强光子与半导体量子点和金刚石纳米晶体中的光学中心的相互作用。将开发量子动力学建模以提供支持。 光子源的工程设计需要调整光场和原子发射器之间的相互作用。这需要对经典和量子场论以及固态物理学的综合理解。通过适当的腔设计,可以使腔模和单个发射体之间的相干相互作用主导通常导致非相干发射的衰减机制。这种强耦合将允许腔和发射器之间的能量相干交换,这是量子信息处理的核心。更广泛的影响包括通信和信息处理方面的潜在突破。量子信息技术正在吸引学生参与研究,包括研究生,本科生和REU。在俄勒冈州光学中心,学生参加教学实验室,研讨会,联合小组会议,外部合作者和年度研究务虚会。PI最近为非理科专业的本科生开设了一门课程,名为“互联网背后的物理学”,介绍信息技术的物理基础。计划于2007年出版配套教材。
