* aesthetic information is very difficult to measure, due to the personal and time-random dynamic nature of its “alphabet”.

What about the perception that generates “aesthetic information”? Is it of non-algorithmic nature like perception of the external reality that generates scientific creativity?

The “undecidable character” of chaotic dynamics that underlies all information generation and processing in living matter leads us to “non-computability in practice”, as opposed to “non-computability in principle” resulting from “pure formal logic”

This result comes from classical physics; recent quantum physics

supplies a deeper notion of information

* according to recent research (1995-1998) in quantum theory of computation and communication, the basic texture of the Universe shows a “solidarity”, first experimentally observed in 1997, that recalls Bohmian’s conception of an

“undivided Universe”

* at the quantum level, matter and information become blurred into a kind of supersubstance, i.e.,

a matter-informationsolidary agency which is reminiscent of Bohm’s view

* in classical physics, information is an emergent property from conjugation of external signals with the internal dynamics of the receptor; in quantum theory there are two elementary (i.e. the smallest) informational particles: the “qubit” (information) and the “ebit” (entanglement), both hidden in the very fabric that the Universe is made up of.

* quantum “marks” (qubit and ebit) locked in a quantum state are unwieldy: for them to become information as an emergent objective property they must interact

* like “virtual particles” of quantum field theory, virtual information particles do exist, that are revealed when they interact with real information, as depicted in the Feynman diagram (on next transparency) of the flow of information arising from interaction of particles and an observer

In classical physics, information is always real, like energy is. At the quantum level, information can be both virtual and real, so underlying reality according to the quotation from A. Zeilinger at the beginning of this presentation.

“Information is such a fundamental thing from which quantum theory can be deduced”

(A. Steane)

**Teleportation**

Feynman’s diagrams used to chart the interactions of elementary particles are also applied to describe the flow of information particles: the qubit (the 2-state quantum system) and the ebit (the maximal quantum information in an entangled system).

In the diagram, “clbit” stands for the well-known

classical bit of information.

In the diagram, a qubit interacts with one ebit of an entangled pair, creating real information which goes on to interact with the anti-ebit at the receiving point, remaking the original qubit
