  We propose a method for optical interferometry in telescope arrays assisted
by quantum networks. In our approach, the quantum state of incoming photons
along with an arrival time index is stored in a binary qubit code at each
receiver. Nonlocal retrieval of the quantum state via entanglement-assisted
parity checks at the expected photon arrival rate allows for direct extraction
of the phase difference, effectively circumventing transmission losses between
nodes. Compared to prior proposals, our scheme (based on efficient quantum data
compression) offers an exponential decrease in required entanglement bandwidth.
Experimental implementation is then feasible with near-term technology,
enabling optical imaging of astronomical objects akin to well-established radio
interferometers and pushing resolution beyond what is practically achievable
classically.
