Nonclassical States for Quantum Information Processing

量子信息处理(QIP)的一种光学方法包括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，这种状态可能不太容易受到量子通信系统中错误的影响。用于实现这两种关键资源的实验方法涉及通过参数下转换产生的光子对。该项目通过帮助在密歇根大学物理系建立一个新成立的QIP研究小组的基础设施，侧重于研究和教育的整合。对从事研究的研究生的支持，以及物理专业本科生参与的机会，是该计划的关键组成部分。该项目还构成了一项将马里兰州一所高中的物理学生与研究联系起来的外展努力的基础。

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.
