Abstract
This paper illustrates the results of an experiment performed in the frame of the Asiago Observatory Stellar Intensity Interferometry program, aimed to exploit the quantum properties of the photon stream emitted from celestial objects. Data are acquired over two telescopes separated by approximately 4 km in photon-counting mode and analyzed in post-processing. The temporal and spatial correlation function g(2) on the bright star Vega has been successfully measured at zero baseline and at a ~2 km baseline. The result is fully consistent with that expected for a source with the angular diameter of Vega (approximately 3.3 mas).
