Optimal rectification by strongly coupled spins
T. Werlang, M. A. Marchiori, M. F. Cornelio +1
We study heat transport in a pair of strongly coupled spins. In particular, we present a condition for optimal rectification, i.e., flow of heat in one direction and complete isola…
Monogamy of entanglement of formation
Thiago R. de Oliveira, Marcio F. Cornelio, Felipe F. Fanchini
It is well known that a particle cannot freely share entanglement with two or more particles. This restriction is generally called monogamy. However the formal quantification of su…
Multipartite monogamy of the concurrence
Marcio F. Cornelio
Monogamy of entanglement is generally discussed using a bipartite entanglement measure as an upper bound. Here we discuss a new kind of monogamous relation where the upper bound is…
Emergence of the pointer basis through the dynamics of correlations
M. F. Cornelio, O. Jiménez Farías, F. F. Fanchini +7
We use the classical correlation between a quantum system being measured and its measurement apparatus to analyze the amount of information being retrieved in a quantum measurement…
Entanglement irreversibility from quantum discord and quantum deficit
Marcio F. Cornelio, Marcos C. de Oliveira, Felipe F. Fanchini
We relate the problem of irreversibility of entanglement with the recently defined measures of quantum correlation - quantum discord and one-way quantum deficit. We show that the e…
Strong superadditivity and monogamy of the Renyi measure of entanglement
Marcio F. Cornelio, Marcos C. de Oliveira
Employing the quantum Rényi -entropies as a measure of entanglement, we numerically find the violation of the strong superadditivity inequality for a system composed of four qub…
