Title: Skipper-CCD: a single-photon imaging sensor up to several thousand electrons per pixel for Quantum Imaging applicationshttps://www.youtube.com/watch?v=cNaVjPVILjcAbstract: Skipper-CCDs are single-photon counting imaging sensors originally developed for low mass direct dark matter searches (SENSEI) in a collaborative effort between Lawrence Berkeley National Laboratory and Fermi National Accelerator Laboratory (Fermilab) [1]. The ability of these sensors to count electrons with high signal to noise, up to several thousand electrons per pixel, makes them a unique tool for quantum imaging experiments. One of our goals is to develop the Skipper-CCD as a new tool for quantum imaging experiments and to explore quantum imaging as a new technique to search for dark photons and axions. During the last year at Fermilab, we have demonstrated the existing sensors for imaging twin photon pairs, observing the spatial correlation between them, and we have developed the theoretical and experimental fundamentals for dark photon searches by means of quantum imaging. In the coming years, we will build on these accomplishments to develop the full potential of Skipper-CCD in Quantum Information Science. As part of this effort, a new laboratory called LAMBDA, completely dedicated to Skipper-CCD technology, will be built in the Physics Department of the University of Buenos Aires, in Argentina.[1] Tiffenberg et al.
