Higher-resolution imaging of distant sources using imperfect quantum resources.

We show how the baseline size between telescopes, that determines the angular resolution, used in optical interferometric arrays can be increased by using a shared, possibly non-maximally-entangled, quantum state. We analyse how the rate of entagled-state production in the quantum repeater network needs to scale with the baseline size while maintaining interferometric sensitivity.
