Production of Information and Entropy in measurement of entangled states

Abstract

Problem of classification of all the set of entangled states is considered. Invariance of entangled states relative to transformations from a group of symmetry of qubit space leads to classification of all states of the system through irreducible representations from that group. Excess of entropy of a subsystem over entropy of the whole system indicates the presence of entaglement in the system.
