Quantum technology is mostly known in the field of computing but has important applications for sensing and imaging. I will overview some exciting opportunities for a crossover of quantum photonics with life sciences. Ongoing activities in our research team at the University of Glasgow develop quantum technologies to build next generation quantum microscopes and to the problem sensing and imaging of the brain. The technologies revolve around the use of single-photon counting detectors and cameras for applications that require not only low light sensitivity but also high temporal resolution and high frame rates. Quantum interference can then improve the temporal resolution for example in fluorescence lifetime imaging by 1000x compared to standard approaches. We will also give an overview of our work aimed at transmitting light through the head and the use of light to detect neurodegeneration.
