    "abstract": "A new measure of information in quantum mechanics is proposed which takes\ninto account that for quantum systems the only feature known before an\nexperiment is performed are the probabilities for various events to occur. The\nsum of the individual measures of information for mutually complementary\nobservations is invariant under the choice of the particular set of\ncomplementary observations and conserved if there is no information exchange\nwith an environment. That operational quantum information invariant results in\nN bits of information for a system consisting of N qubits.",
