The "noncausal causality" of quantum information

The paper is concentrated on the special changes of the conception of causality from quantum mechanics to quantum information, meaning as a background the revolution implemented by the former to classical physics and science after Max Born’s probabilistic reinterpretation of wave function: (1) quantum information describes the general case of the relation of wave functions; (2) it keeps the physical description to be causal by the conservation of quantum information; (3) it introduces inverse causality, “backwards in time”; (4) it involves a kind of “bidirectional causality” unifying (4.1) the classical determinism of cause and effect, (4.2) the probabilistic causality of quantum mechanics, and (4.3) the reversibility of any coherent state; (5) it identifies determinism with the function successor in Peano arithmetic, and its proper generalized causality with the information function successor in Hilbert arithmetic.
