Teleportation The Impossible Leap

A science fiction staple and a fantasy of those with long commutes, teleportation--sending something from here to there in the blink of an eye--has long seemed likely to remain a fictional construct. But as Darling explains in this marvelous work, teleportation in one form or another has been happening in laboratories for a few years and is on its way to becoming a routine part of life--at least for information. Darling (Equations of Eternity) uses lively, companionable prose to explain such heady subjects as quantum mechanics, the property of entanglement (which Einstein referred to as "spooky action at a distance") and information theory. While these concepts appear to fly in the face of reason, the author is able to make sense of them and put them in the context of other new ideas that at first may be impossible to accept. After tracing the history of developments that became key to teleportation, the text delves into its use for secret communications, massive parallel data processing and investigating quantum mechanics; it also examines the moral, spiritual and philosophical questions that will arise if "beaming" people up ever becomes possible. Suitable for a pop-science audience, especially those looking for a way into quantum mechanics and wave-particle duality, this singular work deserves a wide audience. Agent, Patricia van der Leun.
