Teleportation [PDF ebook] 
The Impossible Leap

An authoritative, entertaining examination of the ultimate thrill ride Until recently the stuff of sci-fi fiction and Star Trek reruns, teleportation has become a reality-for subatomic particles at least. In this eye-opening book, science author David Darling follows the remarkable evolution of teleportation, visiting the key labs that have cradled this cutting-edge science and relating the all-too-human stories behind its birth. He ties in the fast emerging fields of cryptography and quantum computing, tackles some thorny philosophical questions (for instance, can a soul be teleported?), and asks when and how humans may be able to "beam up."
