Entangled clouds raise hope of teleportation

Using quantum entanglement effects, Danish physicists have made two samples of trillions of atoms interact at a distance. This has profound implications for quantum computing and communications — and could conceivably lead one day to instant transportation, Star Trek style. Entangled states have been demonstrated before, but this was done with trillions of atoms and laser light. The entangled spin state lasted 0.5 milliseconds, a long time in this context
