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，改进的传感将使人们能够更准确地进行距离测量，从而使任何商业产品的性能都更好。成像是一种特殊的传感，在这种传感中，人们想要在场景中的一组点上进行准确的测量。过去几十年的研究表明，量子测量方法可以用来获得相对于经典(非量子)测量所能达到的精度而言更高的测量精度。我们建议的工作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呈现出不同的背景。为了加强这些学术参与者，我们还在加拿大或来自海外的五个与加拿大科学有密切联系的非学术合作机构。我们的工作计划是多样化的。我们在原子量子传感、生物量子传感、量子成像和显微镜、人工智能量子传感、量子激光雷达等方面做出了重大努力。我们的研究方法包括一些新的概念，如同时考虑电偶极子和磁偶极子耦合的非线性混频，以及用强抽运代替自发参数下转换中的泵浦光束，从而产生许多光子对。我们的管理结构旨在让不同的人和组织参与任何决策过程。

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.
