Quantum Bioimaging Facility across the Univeristy of Toronto

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.
