[share_ebook] Teleportation: The Impossible Leap

• Author: David Darling

Teleportation is cool. Captain Kirk stands on the pad, and Scotty beams him up, down, and all around. Cooler is that teleportation may become practical soon. Computer scientists abetted by physicists are now exploiting quantum phenomena to teleport photons, mostly, and some atoms, though not all that far. As for anything big enough to see, well . . . Darling predicts that inanimate objects, at least, will be teleported eventually, and he broaches human teleportation and the philosophical, religious, and social questions it may raise fore and aft of the enlightening main text here, which begins with light. Darling chronicles the varying historical fortunes and the eventual merger of particle and wave theories of light before turning to the quantum phenomenon of entanglement and information theorists' appropriation of quantum mechanics because information comes in particles (bits), too. Cryptographers then wondered whether in entanglement lay the means to create absolutely secure messages. Darling's descriptions of recent experiments are readable, if not always transparent, and the -science--historical text that surrounds them is both. Terrific science writing.
