Predominance of entanglement of formation over quantum discord under quantum channels
Steve Campbell
We present a study of the behavior of two different figures of merit for quantum correlations, entanglement of formation and quantum discord, under quantum channels showing how the…

Critical assessment of two-qubit post-Markovian master equations
S. Campbell, A. Smirne, L. Mazzola +4
A post-Markovian master equation has been recently proposed as a tool to describe the evolution of a system coupled to a memory-keeping environment [A. Shabani and D. A. Lidar, Phy…

Global Quantum Correlation in the Ising model
Steve Campbell, Laura Mazzola, Mauro Paternostro
We study quantum correlations in an isotropic Ising ring under the effects of a transverse magnetic field. After characterizing the behavior of two-spin quantum correlations, we ex…
