'''[[Quantum mechanics]] and [[Theory of relativity|relativity]] theory''' are two of the foundational stones of [[theoretical physics]], while [[information theory]] is one of the most widely applied of all theories in [[mathematics]].

(contracted; show full) to [[general relativity]]; in fact, Hawking radiation should occur in various physical situations ''completely unrelated to gravitation''-- except formally-- 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 [[q
auantum information theory]].  This work really does involve both information theory and quantum theory in essential ways.

The following questions naturally arise:
*Fundamentally, what is information in physics?
*How can information be obtained physically?
*By what means can information be transmitted?
*Can information be complete?
