Entanglement and Some Recent Applications of Quantum Mechanics
There are unique features of quantum mechanics that only appear for two or more identical particles. Among them, the concept of entanglement is not only fundamental in the discussion of the validity of quantum mechanics (Sects. 12.4.2 and 12.4.3), but it has also become, during the last twenty years, a central tool in the emerging field of quantum information. We will not attempt to give a complete description of these recent developments. Rather, we will use the respectable knowledge of quantum mechanics which readers should now have in order to illustrate these new uses with pertinent examples.
