I will take a look. Thanks.
Hmm.. Still very aristotelician. It can't work, but that kind of
reflexion might help to solve the problem. Hmm still very fuzzy on the
basic assumptions ..., his definition of information assume a universe
(and a machine).

Existence of an information unit as a postulate of quantum theory

Does information play a significant role in the foundations of
physics? Information is the abstraction that allows us to refer to
the states of systems when we choose to ignore the systems
themselves. This is only possible in very particular frameworks,
like in classical or quantum theory, or more generally, whenever
there exists an information unit such that the state of any system
can be reversibly encoded in a sufficient number of such units. In
this work we show how the abstract formalism of quantum theory can
be deduced solely from the existence of an information unit with
suitable properties, together with two further natural assumptions:
the continuity and reversibility of dynamics, and the possibility of
characterizing the state of a composite system by local
measurements. This constitutes a new set of postulates for quantum
theory with a simple and direct physical meaning, like the ones of
special relativity or thermodynamics, and it articulates a strong
connection between physics and information.
