'''[[Quantum mechanics]] and [[Theory of relativity|relativity]] theory''' comprise two of the foundation stones of [[theoretical physics]], and [[information theory]] is one of the most successful of all theories in [[applied mathematics]].

(contracted; show full)y-- but where something closely analogous to an event horizon occurs; this leads to the idea of [[analog gravity]], which includes the notions of [[optical black hole]]s and [[acoustic black hole]]s.)  In addition, in the last decade, the new concept of the [[qubit]] has been intensively developed in the new field sometimes called [[qauntum information theory]].  This work really does involve both information theory and quantum theory in essential ways.

Perhaps motivated by these developments, Carl Hewitt
 (Electrical Engineering, University of Michigan, Emeritus) speculates there should be a new kind of 'information theory' which addresses questions such as these:
*Fundamentally, what is information in physics?
*How can information be obtained physically?
*By what means can information be transmitted?
*Can information be complete?
