Science Magazine has an article giving more detail about China’s quantum satellite achieves ‘spooky action’ at record distance.

Quantum entanglement—physics at its strangest—has moved out of this world and into space. In a study that shows China’s growing mastery of both the quantum world and space science, a team of physicists reports that it sent eerily intertwined quantum particles from a satellite to ground stations separated by 1200 kilometers, smashing the previous world record. The result is a stepping stone to ultrasecure communication networks and, eventually, a space-based quantum internet.

If the idea of quantum entanglement boggles your mind, maybe the following video will help. (Or maybe it will just boggle your mind more).
