Nonlocality and entanglement in the XY model
J. Batle, M. Casas
Nonlocality and quantum entanglement constitute two special features of quantum systems of paramount importance in quantum information theory (QIT). Essentially regarded as identic…
Some features of the state-space trajectories followed by robust entangled four-qubit states during decoherence
A. P. Majtey, A. Borras, A. R. Plastino +2
In a recent work (Borras et al., Phys. Rev. A {\bf 79}, 022108 (2009)), we have determined, for various decoherence channels, four-qubit initial states exhibiting the most robust p…
Jensen Shannon divergence as a measure of the degree of entanglement
A. P. Majtey, A. Borras, M. Casas +2
The notion of distance in Hilbert space is relevant in many scenarios. In particular, distances between quantum states play a central role in quantum information theory. An appropr…
Entanglement and the Lower Bounds on the Speed of Quantum Evolution
A. Borrás, M. Casas, A. R. Plastino +1
The concept of quantum speed limit-time (QSL) was initially introduced as a lower bound to the time interval that a given initial state may need so as to evolve into a state…
Understanding Quantum Entanglement: Qubits, Rebits and the Quaternionic Approach
J. Batle, A. R. Plastino, M. Casas +1
It has been recently pointed out by Caves, Fuchs, and Rungta that real quantum mechanics (that is, quantum mechanics defined over real vector spaces provides an interesting foil th…
Maximally Entangled Mixed States and Conditional Entropies
J. Batle, M. Casas, A. Plastino +1
The maximally entangled mixed states of Munro, James, White, and Kwiat [Phys. Rev. A {\bf 64} (2001) 030302] are shown to exhibit interesting features vis a vis conditional entropi…
