The quantum field theory (QFT) dual paradigm in fundamental physics and the semantic information content and measure in cognitive sciences

摘要

In QIT any quantum system has to be considered, as an "open" system, because always interacting with the background fluctuations of the quantum vacuum. Namely, the Hamiltonian in QIT is always including the quantum system and its inseparable thermal bath, formally "entangled" like an algebra with its co-algebra, according to the principle of the "doubling" of the degrees of freedom (DDF). This is the core of the representation theory of the cognitive neuroscience based on QIT. Moreover, in QIT the probabilities of the quantum states follow a Wigner distribution, based on the notion and the measure of quasi-probability, where negative probabilities are allowed and regions integrated under given expectation values do not represent mutually exclusive states. This means that a computing agent, either natural or artificial in QFT, against the QTM paradigm, is able to change dynamically the basic symbols of its computations. This justifies and not only supposes the definition of the information associated with a Wigner distribution as a "semantic information content", according to the definition and measure of it, defined in the Theory of Strong Semantic Information (TSSI) of L. Floridi.
