A little closer to teleportation and new computers
2012 SCIENCE NEWS TOP 25: 12
The future is calling. In a step toward hacker-proof messaging, physicists this year sent quantum-encoded information zipping over a greater distance than ever before. They also spotted a long-sought particle whose quantum properties could one day be used to develop a superfast futuristic computer.
There’s still no “beam me up” machine, but when it comes to sending information, even instant messaging can’t hold a candle to quantum teleportation. Researchers beam information using a pair of particles “entangled” such that measuring a particular property of one determines that property for the other, even if they are far apart. The information about that property is thus teleported instantaneously between the two.
