Quantum Enhanced Sensing and Imaging (QuEnSI)

我们建议在量子增强传感和成像（QuEnSI）领域建立一个由NCERC资助的联盟。传感和成像是关键的使能技术;它们是大多数工业努力的核心。例如，改进的传感器将允许人们更准确地进行距离测量，从而提高任何商业产品的性能。成像是一种特殊类型的传感，其中人们希望对场景内的点阵列进行精确测量。过去几十年的研究表明，量子测量方法可以应用于获得相对于经典（非量子）测量可实现的精度增强的测量精度。我们的工作计划是将这些知识应用于当今社会遇到的一系列实际问题。为了支持这些目标，我们成立了一个由来自加拿大几所大学的十名科学家组成的团队。这些科学家来自加拿大不同地理区域的大学。他们在性别和学术生涯阶段方面也有不同的背景。为了加强这些学术参与者，我们还确定了加拿大或海外的五个非学术合作机构，这些机构与加拿大科学有着密切的联系。我们的工作计划多种多样。我们主要致力于原子量子传感，生物学量子传感，量子成像和显微镜，人工智能量子传感和量子激光雷达。我们的研究方法包括一些新的概念，如非线性波混频涉及电偶极和磁偶极耦合，并取代泵浦光在自发参量下转换与强泵，使许多光子对的创建。我们的管理结构旨在将不同的人员和组织纳入任何决策过程。

We propose the establishment of an NCERC-funded Alliance in the area of Quantum Enhanced Sensing and Imaging (QuEnSI). Sensing and imaging are key enabling technologies; they lay at the heart of most industrial endeavors. Improved sensing would, for example, allow one to perform distance measurements more accurately, leading to better performance of any commercial product. Imaging is a special kind of sensing, in which one wants to make accurate measurements on an array of points within a scene. Research over the past several decades has shown that quantum measurement methods can be applied to obtain measurement accuracy that is enhanced with respect to accuracy achievable with classical (non-quantum) measurements. Our proposed work intends to apply this knowledge to a slew of practical problems encountered in present society.To support these aims, we have established a team of ten scientists from several universities in Canada. These scientists come from universities at a variety of geographical regions in Canada. They also present diverse background in terms of gender and stage of academic career. To augment these academic players, we have also identified five non-academic partner institutions in Canada or from overseas with a strong connection to Canadian science. Our workplan is diverse. We have major efforts in quantum sensing with atoms, quantum sensing in biology, quantum imaging and microscopy, quantum sensing with artificial intelligence, and quantum lidar. Our research methodology includes some novel concepts such as nonlinear wave mixing involving both electric-dipole and magnetic-dipole coupling and replacing the pump beam in spontaneous parametric downconversion with an intense pump so that many photon pairs are created. Our management structure is intended to bring a diverse set of people and organizations into any decision-making process.
