Quantum Teleportation Breakthrough as Scientists send Data across Cities

While Star Trek-style teleportation is still a long way off, (Yeah right!)researchers have revealed a major breakthrough in the field of quantum travel.
Two separate teams have transferred quantum information over several miles of fibre optic networks in an urban network.
The results could lead to more secure bank accounts, a faster internet and possibly even open the door to the controversial idea of human teleportation.
Quantum teleportation depends on a phenomenon called quantum entanglement, which allows connections to be made between atoms, with their information being sent to others far away.
The entangled particles are connected in such a way that the action of one directly affects the others, even if they are separated over large distances.
Albert Einstein called this 'spooky action at a distance.'
Previous studies have shown atoms teleporting across a room, and light being teleported across the Danube River in Austria.
Now two separate studies, published today in Nature Photonics, have shown quantum teleportation is feasible through optical fibres across cities.
The new research is a step towards building a 'quantum internet', which would be faster, more efficient and more secure than the networks we rely on today.
