Investigations in Quantum Metrology and Quantum Entanglement

量子信息科学(QIS)是研究如何使用符合量子力学定律的系统来执行信息处理任务的跨学科领域。这个项目专注于QIS和高精度测量科学的交叉点上的一系列问题。QIS和测量科学的这种交叉现在被称为量子计量学。将要研究的具体问题包括如何最好地部署物理系统，如原子、光子和微小的工程谐振器，以对电场、磁场和引力场等物理量进行尽可能好的测量，以及如何利用与相互作用系统相关的量子纠缠的奇怪性质来改进此类测量。与该项目相关的博士生将在新墨西哥大学量子信息与控制中心的框架内工作，该中心在为QIS职业培训博士生方面有着良好的记录。CQuIC的学生参加了一系列关于QIS主题的选修课，通过高级别的每周研讨会系列和每周的CQuIC小组会议接触到QIS的跨学科思想，在会议上发布到电子打印服务器arxiv.org上的论文被审查和讨论，学生和博士后在发表技术演讲的艺术上接受强化培训。CQuIC为学生提供了与六个外部合作机构参与研究合作的机会。

Quantum information science (QIS) is the interdisciplinary field that investigates how to use systems obeying the laws of quantum mechanics to perform information-processing tasks. This project is focused on a set of questions that lie at the intersection of QIS and the science of making high-precision measurements. This intersection of QIS and measurement science is now called quantum metrology. The specific questions to be investigated include how best to deploy physical systems, such as atoms and photons and tiny engineered resonators, to make the best possible measurements of such physical quantities as electric and magnetic fields and gravitational fields and how to use the strange property of quantum entanglement associated with interacting systems to improve such measurements.PhD students associated with this project will work within the framework of the Center for Quantum Information and Control at the University of New Mexico, which has a proven track record of training PhD students for careers in QIS. CQuIC students take a sequence of elective courses on QIS topics, are exposed to the interdisciplinary ideas of QIS through a high-level, weekly seminar series and through the weekly CQuIC group meeting, at which papers posted to the e-print server arXiv.org are reviewed and discussed and at which students and postdocs receive intensive training in the art of giving technical talks. CQuIC provides students the opportunity to participate in research collaborations with six external partnering institutions.
