Robustness of Highly Entangled Multi-Qubit States Under Decoherence
A. Borras, A. P. Majtey, A. R. Plastino +2
We investigate the decay of entanglement, due to decoherence, of multi-qubit systems that are initially prepared in highly (in some cases maximally) entangled states. We assume tha…
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…
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…
Werner states and the two-spinors Heisenberg anti-ferromagnet
J. Batle, M. Casas, A. Plastino +1
We ascertain, following ideas of Arnesen, Bose, and Vedral concerning thermal entanglement [Phys. Rev. Lett. {\bf 87} (2001) 017901] and using the statistical tool called {\it entr…
