  • Salagaram, Trisha; Chetty, Nithaya (American Association of Physics Teachers, 2011-11)
    We devise a hierarchy of computational algorithms to enumerate the microstates of a system comprising N independent, distinguishable particles. An important challenge is to cope with integers that increase exponentially ...
  • Borras, A.; Zander, Claudia; Casas, Montserrat; Plastino, Angel Ricardo (Angelo) (EPLA, 2008)
    Entanglement is closely related to some fundamental features of the dynamics of composite quantum systems: quantum entanglement enhances the “speed” of evolution of certain quantum states, as measured by the time required ...
  • Zander, Claudia; Plastino, Angel Ricardo (Angelo); Casas, Montserrat (American Institute of Physics, 2007-03-16)
    There exists an interesting relationship between entanglement and the time evolution of composite quantum systems: quantum entanglement enhances the 'speed' of evolution of certain quantum states, as measured by the time ...
  • Zander, Claudia; Borras, A.; Plastino, Angel Ricardo (Angelo); Casas, Montserrat (Institute of Physics, 2013-02-12)
    The time needed by a quantum system to reach a state fully distinguishable from the original one provides a natural way of determining how fast the corresponding dynamical evolution is. This orthogonality time admits a ...
  • Zander, Claudia; Plastino, Angel Ricardo (Angelo); Casas, Montserrat (Springer, 2012-01)
    Entanglement criteria for general (pure or mixed) states of systems consisting of two identical fermions are introduced. These criteria are based on appropriate inequalities involving the entropy of the global density ...
  • Zander, Claudia (AOSIS Open Journals, 2013)
