An essential overview of quantum information

Information, whether inscribed as a mark on a stone tablet or
encoded as a magnetic domain on a hard drive, must be stored in a
physical object and thus made subject to the laws of physics.
Traditionally, information processing such as computation occurred
in a framework governed by laws of classical physics. However,
information can also be stored and processed using the states of
matter described by non-classical quantum theory. Understanding
this quantum information, a fundamentally different type of
information, has been a major project of physicists and information
theorists in recent years, and recent experimental research has
started to yield promising results.

Quantum Approach to Informatics fills the need for a concise
introduction to this burgeoning new field, offering an intuitive
approach for readers in both the physics and information science
communities, as well as in related fields. Only a basic background
in quantum theory is required, and the text keeps the focus on
bringing this theory to bear on contemporary informatics. Instead
of proofs and other highly formal structures, detailed examples
present the material, making this a uniquely accessible
introduction to quantum informatics.

Topics covered include:

* An introduction to quantum information and the qubit

* Concepts and methods of quantum theory important for
informatics

* 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 exciting
new application of quantum theory to informatics, Quantum Approach
to Informatics provides students and researchers in physics and
information science, as well as other interested readers with some
scientific background, with an essential overview of the field.

Autor

STIG STENHOLM, PhD, was Professor of Laser Physics and Quantum Optics at the Royal Institute of Technology, Stockholm, up until his retirement in 2004. He previously held positions at the University of Helsinki and the Academy of Finland. His research interests include laser physics and spectroscopy, quantum optics, laser-induced atomic and molecular processes, quantum information, and quantum dynamics. KALLE-ANTTI SUOMINEN, PhD, is Professor of Physics at the University of Turku in Finland. He previously worked at the Helsinki Institute of Physics and the University of Oxford. His current research concentrates on field-induced quantum dynamics in atomic and molecular systems, cold atomic collisions, and Bose-Einstein condensates of atoms and molecules.
