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…
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…
On the metric character of the quantum Jensen-Shannon divergence
P. W. Lamberti, A. P. Majtey, A. Borras +2
In a recent paper, the generalization of the Jensen Shannon divergence (JSD) in the context of quantum theory has been studied (Phys. Rev. A 72, 052310 (2005)). This distance betwe…
