Abstract

We describe a new technique of quantum astrometry, which potentially can improve the resolution of optical interferometers by orders of magnitude. The approach requires fast imaging of single photons with sub-nanosecond resolution, greatly benefiting from recent advances in photodetection technologies. We also describe results of first proof of principle measurements and lay out future plans.
