Sudden death of entanglement in fermionic systems under collective decoherence
D. G. Bussandri, A. P. Majtey, A. Valdés-Hernández
We analyze the dynamics of entanglement due to decoherence in a system of two identical fermions with spin interacting with a global bosonic environment. We resort to an appr…
Generalized Holevo theorem and distinguishability notions
Diego G. Bussandri, Pedro W. Lamberti
We present a generalization of the Holevo theorem by means of distances used in the definition of distinguishability of states, showing that each one leads to an alternative Holevo…
Behavior of quantum correlations under nondissipative decoherence by means of the correlation matrix
D. G. Bussandri, T. M. Osán, A. P. Majtey +1
In this paper we use the Fano representation of two-qubit states from which we can identify a correlation matrix containing the information about the classical and quantum correlat…
Non-commutative measure of quantum correlations under local operations
D. G. Bussandri, A. P. Majtey, A. Valdés-Hernández
We study some desirable properties of recently introduced measures of quantum correlations based on the amount of non-commutativity quantified by the Hilbert-Schmidt norm (Sci Rep…
Generalized approach to quantify correlations in bipartite quantum systems
D. G. Bussandri, A. P. Majtey, P. W. Lamberti +1
In this work we developed a general approach to the problem of detecting and quantifying different kind of correlations in bipartite quantum systems. Our method is based on the use…
Monoparametric family of metrics derived from classical Jensen-Shannon divergence
Tristán M. Osán, Diego G. Bussandri, Pedro W. Lamberti
Jensen-Shannon divergence is a well known multi-purpose measure of dissimilarity between probability distributions. It has been proven that the square root of this quantity is a tr…
