 Hanbury Brown and Twiss pioneered the use of photon correlations and photon statistics in augmenting astronomical measurements already in the 1950s. Technological advances have made parallelized characterization of photon statistics beyond the time domain feasible and opened multiple opportunities in imaging and spectroscopy [1], ranging from an unprecedented ability to characterize transient highly excited states in quantum emitters of light such as semiconductor nanocrystals [2] to the exploitation of nonclassical photon statistics in superresolution imaging [3]. Following an overview of these, I will discuss the current status and potential future applications of large format single photon detector arrays.
