  • M. Guillaume AUBRUN         (Université Lyon 1)
  • M. Fabrice GAMBOA         (Université Toulouse III - Paul Sabatier)
  • Mme Maria JIVULESCU         (Politehnica University of Timisoara)
  • M. Ion NECHITA         (Université Toulouse III - Paul Sabatier)
  • M. Clément PELLEGRINI         (Université Toulouse III - Paul Sabatier)
  • M. Michael WOLF         (Technical University of Munich)


PhD thesis abstract:
This thesis studies quantum cloning and related quantum entanglement problems using fundamental concepts of representation theory, in particular those associated with the symmetric group. The research explores Schur-Weyl duality and its extensions, which allow efficient representation and manipulation of quantum systems, providing a valuable tool for quantum information theory. A main application of Schur-Weyl duality is the quantum cloning problem, which is studied both for cases 1 → 2 and for the more general cases 1 → N, providing new insights into the constraints imposed by the no-cloning theorem. The study is then extended to a more general quantum entanglement problem on a complete graph. The thesis is organised into chapters on Schur-Weyl duality, the mathematical foundations of quantum mechanics, quantum cloning problems and quantum entanglement problems, with an appendix providing an overview of representation theory.
