What is entanglement? Its a quantum process that connects two particles (say, photons of light) in such a way that changes to one of the particles are reflectedinstantlyin the other, even if theyre light-years apart. Why do we care? The possibilities read like something out of science fiction: Communications devices that could span the stars Codes that simply cannot be broken lest the very laws of physics be overturned Computers that dwarf todays machines in speed and power Teleportation And lots more. In Quantum Entanglement, veteran science writer Brian Clegg has written an exceptionally readable account of entanglement, its history, and its application. Whether youre a popular science fan, or just someone interested in the marvelous possibilities coming down the quantum road, you will find much to marvel, illuminate, and delight.
