  We propose a method to build an astronomical interferometer using continuous
variable quantum teleportation to overcome the transmission loss between
distant telescopes. The scheme relies on two-mode squeezed states shared by
distant telescopes as entanglement resources, which are distributed using
continuous variable quantum repeaters. We find the optimal measurement on the
teleported states, which uses beam-splitters and photon-number-resolved
detection. Compared to prior proposals relying on discrete states, our scheme
has the advantages of using linear optics to implement the scheme without
wasting stellar photons and making use of multiphoton events, which are
regarded as noise in previous discrete schemes.
