Physicists Quantum Teleport Photons Over 88 Miles
An international team of researchers has published their paper demonstrating quantum teleportation between two Canary Islands. While quantum teleportation doesn’t lead to instantaneous communication, what it does lead to is incredibly secure communications. That’s because no matter what instructions the sender sends over normal communications channels, those instructions are completely useless without the receiver’s entangled photon. And the sender doesn’t have to know the location of the receiver’s entangled photon. It could be anywhere – there’s no way to track it.
Of course, there’s still a long way to go – decades, perhaps – before this produces any kind of practical communications device. These researchers, however, are eager to move on to the next step – quantum teleportation between the Earth’s surface and a satellite.
