Quantum entanglement and information

Summary form only given. The notion of entanglement was coined by Erwin Schrodinger in order to signify the peculiar properties of quantum correlations. Entanglement is at the heart of the Einstein-Podolsky-Rosen paradox and Bell´s theorem. While, originally, entanglement was considered to be a very important fundamental concept in quantum mechanics leading to such concepts as quantum nonlocality, entanglement in recent years has turned out to be the major concept in novel quantum ways of transmitting and processing information. In the tutorial a very simple conceptual introduction into the essence of entanglement is followed by a presentation of how to produce entangled states. The tutorial concludes with a discussion of quantum cryptography, quantum computation and quantum teleportation.
