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.

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，并研究一种新型的纠缠光态，这种纠缠光态在量子通信系统中可能不太容易出错。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。该项目的重点是研究和教育的整合，帮助建立一个新成立的QIP研究小组在UMBC物理系的基础设施。对从事研究的研究生的支持，以及本科物理专业学生参与的机会，是该计划的关键组成部分。该项目还形成了一个外展工作的基础，该工作将马里兰州一所高中的物理学生与研究联系起来。
