It has been recently pointed out [V. Giovannetti, S. Lloyd, and L. Maccone, Europhys. Lett. 62, 615 (2003)] that, for certain classes of states, quantum entanglement enhances the …

Nonlocality and quantum entanglement constitute two special aspects of the quantum correlations existing in quantum systems, which are of paramount importance in quantum …
The concept of quantum speed limit-time (QSL) was initially introduced as a lower bound to the time interval that a given initial state ψ I may need so as to evolve into a state orthogonal …

We analyze how a maximally entangled state of two qubits (eg, the singlet ψ s) is affected by the action of local channels described by completely positive maps E. We analyze the …
Nonlocality for general multiqubit X states is studied in detail. Pure and mixed states are analyzed as far as their maximum amount of nonlocality is concerned, and analytic results …

By recourse to information-theory tools, we study aspects of the dynamics of the interaction between a single trapped ion with a laser field. Despite its simplicity the model we use …
