Bipartite quantum channels using multipartite cluster-type entangled coherent states

P. P. Munhoz, J. A. Roversi, A. Vidiella-Barranco +1

We propose a particular encoding for bipartite entangled states derived from multipartite cluster-type entangled coherent states (CTECSs). We investigate the effects of amplitude d…

Entanglement versus Quantum Discord in Two Coupled Double Quantum Dots

F. F. Fanchini, L. K. Castelano, A. O. Caldeira

We study the dynamics of quantum correlations of two coupled double quantum dots containing two excess electrons. The dissipation is included through the contact with an oscillator…

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…
