What do we propose to use this grant for: In this NSERC RTI grant the team requests funding to procure a pair of detectors that are capable of detecting single units of light (photons) with efficiency larger than 80 %. These detectors are pivotal to form the chief building block in a quantum, entangled-photon-based microscope. When developed at the departments of Physics and ECE, this world-first microscope will be placed in a major characterization facility within the Ontario Cancer Institute at the University of Toronto. Without the detectors requested here, this new direction of research cannot be pursued as existing detectors have 4 times less sensitivity and 10 times higher noise. The detector pair is based on superconducting active layer (namely NbN) and costs $148,200.00 CAD. This cost includes the detectors, their read-out electronics, cooling cryogenic cryostat and its associated detector mounts. This is the only technology by which low energy entangled photon sources (wavelengths > 1000 nm) can be detected with over 80 % efficiency and is pivotal for quantum imaging.

我们建议将这笔赠款用于什么：在这笔NSERC RTI赠款中，该团队请求获得资金，以采购一对能够以高于80%的效率探测单位光(光子)的探测器。这些探测器是构成量子纠缠光子显微镜的主要组成部分的关键。当在物理系和欧洲经委会开发时，这种世界第一的显微镜将被放置在多伦多大学安大略省癌症研究所的一个主要表征设施中。如果没有这里要求的探测器，这一新的研究方向就无法进行，因为现有的探测器灵敏度低4倍，噪声高10倍。探测器对基于超导有源层(即NBN)，成本为148,200.00加元。这笔费用包括探测器、它们的读出电子设备、冷却低温恒温器及其相关的探测器支架。这是唯一一种能够以80%以上的效率探测低能纠缠光子源(波长1000 nm)的技术，是量子成像的关键。
