Tiny quantum computers could help create giant telescopes

Harvard researchers have demonstrated that tiny quantum memory chips — made from atomic-scale defects in diamonds — can store and combine light signals from two separate telescope-like receivers, mimicking a single massive telescope. In a proof-of-concept experiment, two receivers just six meters apart but connected by 1.5 kilometers of fiber produced sharp interference patterns. This could eventually allow small telescopes to image exoplanets and distant stars with extraordinary resolution.
