EPTThe earliest expirements achieved teleportation, of photons, covering only a few meters. That record was broken this year when scientists were able to teleport as far as 100 kilometers. But the lastest success was able to teleport about 150 kilometers, from one of the canary island to another.
The most immediate use of this technology is through security and quantum computation. But scientists have bigger plans in mind - human teleportation.
Quantum teleportation relies on the phenomenon of entanglement, through which quantum particles share a fragile, invisible link across space. Two entangled photons, for instance, can have correlated, opposite polarization states—if one photon is vertically polarized, for instance, the other must be horizontally polarized. But, thanks to the intricacies of quantum mechanics, each photon’s specific polarization remains undecided until one of them is measured. At that instant the other photon’s polarization snaps into its opposing orientation, even if many kilometers have come between the entangled pair.
I hope to see this technology within our lifetime.
