A little closer to teleportation and new computers

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.
One research team, based in China, entangled groups of photons 97 kilometers apart in the air above a Chinese lake. The scientist
