As the title indicates, this book explores the quantum subtleties, i.e., entanglement and quantum nonlocality, of the world on a small scale. A celebrated result of the late John Stewart Bell provides specific cases where the Einstein-Podolsky-Rosen paradox would be inconsistent with the predictions of quantum mechanics theory. Gisin’s book covers the counterintuitive concept of entanglement which posits a ubiquitous randomness capable of manifesting itself simultaneously in more than one place. This is a complicated notion to absorb, and the author deserves credit for a careful presentation with helpful examples. This book will be of interest and value to everyone curious about the foundational problems of quantum mechanics and their fascinating applications, such as cryptography and teleportation.
