Almost all quantum states have non-classical correlations
A. Ferraro, L. Aolita, D. Cavalcanti +2
Quantum discord quantifies non-classical correlations in a quantum system including those not captured by entanglement. Thus, only states with zero discord exhibit strictly classic…

Open-system dynamics of graph-state entanglement
Daniel Cavalcanti, Rafael Chaves, Leandro Aolita +2
We consider graph states of arbitrary number of particles undergoing generic decoherence. We present methods to obtain lower and upper bounds for the system's entanglement in terms…
