Abstract

Long baseline optical interferometry, by combining the lights from widely-distributed telescopes, is shown to afford pronounced improvement in the imaging resolution in comparison with a single telescope. However, the noise and photon loss in the transmission between the telescopes would limit the length of baseline of interferometer to a few hundred meters. Here, we present a scheme for enhancement of long baseline optical interferometer by using quantum resources- noiseless linear amplifier (NLA) and displacement operation at the photon transmission channels. We exhibit this enhancement quantitatively by calculating higher fisher information compared with those of conventional optical interferometer.
