An essential overview of quantum information
Information, whether inscribed as a mark on a stone tablet orencoded as a magnetic domain on a hard drive, must be stored in aphysical object and thus made subject to the laws of physics.Traditionally, information processing such as computation occurredin a framework governed by laws of classical physics. However,information can also be stored and processed using the states ofmatter described by non-classical quantum theory. Understandingthis quantum information, a fundamentally different type ofinformation, has been a major project of physicists and informationtheorists in recent years, and recent experimental research hasstarted to yield promising results.
Quantum Approach to Informatics fills the need for a conciseintroduction to this burgeoning new field, offering an intuitiveapproach for readers in both the physics and information sciencecommunities, as well as in related fields. Only a basic backgroundin quantum theory is required, and the text keeps the focus onbringing this theory to bear on contemporary informatics. Insteadof proofs and other highly formal structures, detailed examplespresent the material, making this a uniquely accessibleintroduction to quantum informatics.
Topics covered include:
* An introduction to quantum information and the qubit
* Concepts and methods of quantum theory important forinformatics
* The application of information concepts to quantum physics
* Quantum information processing and computing
* Quantum gates
* Error correction using quantum-based methods
* Physical realizations of quantum computing circuits
A helpful and economical resource for understanding this excitingnew application of quantum theory to informatics, Quantum Approachto Informatics provides students and researchers in physics andinformation science, as well as other interested readers with somescientific background, with an essential overview of the field.
