Thermal and Magnetic Quantum Discord in Heisenberg models
T. Werlang, Gustavo Rigolin
We investigate how the quantum correlations (quantum discord) of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium depends on the temperature (T) of the bath…
Non-Markovian Dynamics of Quantum Discord
F. F. Fanchini, T. Werlang, C. A. Brasil +2
We evaluate the quantum discord dynamics of two qubits in independent and common non-Markovian environments. We compare the dynamics of entanglement with that of quantum discord. F…
System-reservoir dynamics of quantum and classical correlations
J. Maziero, T. Werlang, F. F. Fanchini +2
We address the system-reservoir dynamics of classical and quantum correlations in the decoherence phenomenon, regarding a two qubit composite system interacting with two independen…
Robustness of quantum discord to sudden death
T. Werlang, S. Souza, F. F. Fanchini +1
We calculate the dissipative dynamics of two-qubit quantum discord under Markovian environments. We analyze various dissipative channels such as dephasing, depolarizing, and genera…
