Default The Race to Bring Quantum Teleportation to Your World



Quote:
There is an international quantum teleportation space race heating up. Around the world, countries are investing time and millions of dollars into the technology, which uses satellites to beam bits of quantum information down from the sky and and could profoundly change worldwide communication.

This is not a maybe-sort-of-one-day quantum technology. Quantum teleportation has been proven experimentally many times over and researchers are now eyeing the heavens as their next big leap forward. Most of what remains are the nuts and bolts engineering challenges (and some more money) before it becomes a thing of the present.

Though it may be disappointing to hear, quantum teleportation is not about instantly sending a person or object between two places – this is no “Beam me up, Scotty,” or “Bampf!” Instead, the technique involves the perhaps even freakier task of separating a subatomic particle from its quantum state.

“Once you disembody the state of one of particle, you can then recreate the particle in remote copy,” said physicist and computer scientist Charles Bennett of IBM, who co-authored the first paper on quantum teleportation in 1993.
