Abstract

Long baseline weak-thermal-light interferometry is widely used for retrieving astronomical information from an array of telescopes. However, optic loss in the baseline severely limits the length of baseline and thus limits the resolution of interferometers. In this paper, we consider the elimination of optic loss with quantum noiseless linear amplification (NLA). With a success probability of 1.98 × 10^-3 one could implement a 100 km long baseline interferometry via 1550 nm quantum communication. This shows the power quantum information technique and its application in astronomic interferometry. Finally, the comparison with recent entanglement-assisted method is also investigated.
