Quantum Chance: Nonlocality, Teleportation and Other Quantum Marvels

Quantum physics, which offers an explanation of the world onthe smallestscale, has fundamental implications that pose a serious challenge to ordinary logic. Particularly counterintuitive is the notion of entanglement, which has been explored for the past 30 years and posits an ubiquitous randomness capable of manifesting itself simultaneously in more than one place. This amazing 'non-locality' is more than just an abstractcuriosity or paradox: it has entirely down-to-earth applications in cryptography, serving for exampleto protect financial information; it also has enabled the demonstration of 'quantum teleportation', whose infinite possibilities even science-fiction writers can scarcely imagine. This delightful and conciseexposition does notavoid thedeep logical difficulties of quantum physics, but gives the reader the insights needed to appreciate them. From 'Bell's Theorem' to experiments in quantum entanglement, the reader will gain asolid understanding of one of the most fascinating areas of contemporary physics.
