Quantum teleportation is poised to change the world.

It sounds like science fiction – that the quantum state of one system can be transferred, or ‘teleported’, to another system a great distance away at close to the speed of light.

It’s real, and it has been proven – at relatively small scales. But if quantum computers are ever going to communicate across large networks, they’re going to need a way to send a lot of quantum information at once – which means scaling it up.
