Quantum resources of the steady-state of three coupled qubits: Microscopic versus Phenomenological model
E. C. Diniz, A. C. S. Costa, L. K. Castelano
Quantum resources, such as entanglement, steering, and Bell nonlocality, are evaluated for three coupled qubits in the steady-state configuration. We employ the phenomenological ma…

System-environment correlations for dephasing two-qubit states coupled to thermal baths
A. C. S. Costa, M. W. Beims, W. T. Strunz
Based on the exact dynamics of a two-qubit system and environment, we investigate system-environment (SE) quantum and classical correlations. The coupling is chosen to represent a…
