Physicists in China have revealed the details on their ground-breaking experiment to achieve ‘ultra-long-distance quantum teleportation,’ which could pave the way for a global quantum internet.
In a major breakthrough, the team established the first ground-to-satellite quantum network, which allowed them to transmit a photon from an entangled pair up to 870 miles (1,400 kilometers).
Entangled photons theoretically maintain their link across any distance, and have potential to revolutionize secure communications – but, scientists have previously only managed to maintain the bond for about 62 miles (100 km).
