Using Quantum Memory To Uncover The Mysteries Of The Universe

A Harvard-led team demonstrated quantum memories in diamond chips that can store and teleport photon information between two telescopes.

The experiment produced interference patterns over an effective 1.5 km separation, extending the baseline of optical interferometry.

By using entanglement to link telescopes, the approach could bypass light-loss limits that constrain conventional interferometry.

If scaled up, the technique could enable much larger effective telescopes and sharper images of distant cosmic objects.
