Computational difficulties associated with the method are described and a method to overcome them in several nontrivial cases is presented. For the quantum case, a general method to analyze quantum correlations in the sequential measurement scenario is provided, which allows computation of the maximal correlations. Such a method has a direct application for computation of maximal quantum violations of Leggett-Garg inequalities and it is relevant in the analysis of non-contextuality tests. Finally, possible applications of the results for quantum information tasks are discussed.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Quantum theoryQuantum computersSpintronicsQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Quantum theory.Quantum computers.Spintronics.Quantum Physics.Quantum Information Technology, Spintronics.530.12Budroni Costantinoauthttp://id.loc.gov/vocabulary/relators/aut814117MiAaPQMiAaPQMiAaPQBOOK9910254610203321Temporal Quantum Correlations and Hidden Variable Models1818760UNINA
