A quantum internet would be much faster and more secure than the one you’re using right this second – and now such a network may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Quantum entanglement is a strange phenomenon that sounds like science fiction to our classical-physics-focused minds. Basically, two or more particles can become so entwined that changing the state of one instantly changes that of its partners – no matter how far apart they are.
