Information insights

Berry Groisman

The method of using concepts and insight from quantum information theory in order to solve problems in reversible classical computing (introduced in Ref. [1]) have been generalized to irreversible classical computing. The method have been successfully tested on two computational tasks. Several basic logic gates have been analyzed and the nonlocal content of the associate quantum transformations have been calculated. The results provide us with new interesting insight into the notion of complexity of logic operations.

Quantum information theory is a rich and sophisticated physical theory that provides new insights into solving the conceptual difficulties in quantum theory. However, while informational concept to solve the conceptual difficulties in quantum mechanics is used, immaterialism and instrumentalism also prevails. We need to explore the new insights into quantum world using informational concept. On the other hand, it is necessary to keep a properly skeptical attitude to immaterialism and instrumentalism.

Information theory has its particles, bits and qubits, just as physics has electrons and photons. However, in physics we have a special category of objects with no clear counterparts in information theory: quasiparticles. They are introduced to simplify complex emergent phenomena making otherwise very difficult calculations possible and providing additional insight into the inner workings of the system. We show that we can adopt a similar approach in information theory. We introduce the hyperbits, information quasiparticles which we prove to be a resource equivalent to entanglement and classical communication, and we give examples of how they can be used to simplify calculations and get more insight into communication protocols.
