In a well-cited article, Gottesman, Jennewein, and Croke propose a design for a telescope system that uses quantum information to carry out interferometric measurements over light collected in widely-separated telescopes.

This question asks if such a system will exist by 2030. To qualify, the system must:

• Observe light from actual astronomical objects, rather than simulated light.

• Must actually transmit quantum information using the described "quantum repeater" rather than just redirecting the light itself.

• Must make scientific observations that would not be technologically possible using other techniques deployed at the time the observations are made.
