Abstract

Detecting the faint emission of a secondary source in the proximity of the much brighter one has been the most severe obstacle for using direct imaging in searching for exoplanets. Using quantum state discrimination and quantum imaging techniques, we show that one can significantly reduce the probability of error in detecting the presence of a weak secondary source, even when the two sources have small angular separations. Similar techniques can be applied to perform atmospheric spectroscopy.
