  • Entanglement and the quantum brachistochrone problem 
    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 ...
  • Entanglement and the speed of evolution of two interacting qubits 
    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 ...
