Nonclassical States for Quantum Information Processing

量子信息处理（QIP）的光学方法涉及使用单光子和其他非经典光态作为基本资源。该项目的主要目标是开发用于量子计算的高性能单光子源，以及研究一种新型纠缠光态，这种纠缠光态可能不太容易受到量子通信系统中错误的影响。用于实现这两个关键资源的实验方法涉及由参数下转换产生的光子对。该项目通过帮助建立UMBC物理系新成立的QIP研究小组的基础设施，重点关注研究和教育的整合。支持研究生从事研究，以及本科物理专业的参与机会，是该计划的关键组成部分。该项目还为马里兰州一所高中的物理系学生与该研究联系起来的推广工作奠定了基础。

An optical approach to quantum information processing (QIP) involves the use single-photons and other nonclassical light states as fundamental resources. The primary objectives of this project are the development of a high-performance source of single-photons for quantum computing, and the investigation of a new type of entangled optical state that may be less susceptible to errors in quantum communication systems. The experimental methods used for the realization of both of these crucial resources involve photon pairs produced by parametric down-conversion. This project focuses on the integration of research and education by helping to establish the infrastructure of a newly formed QIP research group in the UMBC Physics Department. Support of a graduate student engaged in the research, as well the opportunity for participation by undergraduate physics majors, are key components of the program. The project also forms the basis of an outreach effort that links physics students from a Maryland high school with the research.
