The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics.This review aims to summarize not just quantum computing, but the whole subject of quantum information theory.Information can be identified as the most general thing which must propagate from a cause to an effect.It therefore has a fundamentally important role in the science of physics.However, the mathematical treatment of information, especially information processing, is quite recent, dating from the mid-20th century.This has meant that the full significance of information as a basic concept in physics is only now being discovered.This is especially true in quantum mechanics.The theory of quantum information and computing puts this significance on a firm footing, and has led to some profound and exciting new insights into the natural world.Among these are the use of quantum states to permit the secure transmission of classical information (quantum cryptography), the use of quantum entanglement to permit reliable transmission of quantum states (teleportation), the possibility of preserving quantum coherence in the presence of irreversible noise processes (quantum error correction), and the use of controlled quantum evolution for efficient computation (quantum computation).The common theme of all these insights is the use of quantum entanglement as a computational resource.
