  Quantum resources, such as entanglement, steering, and Bell nonlocality, are
evaluated for three coupled qubits in the steady-state configuration. We employ
the phenomenological master equation and the microscopic master equation to
probe such quantum resources, which provide very different results depending on
the system configuration. In particular, steering and Bell nonlocality are null
within the phenomenological model, while they reach considerable values within
the microscopic model. These results show that the phenomenological approach is
not able to capture all quantum resources of the system. We also provide an
analytical expression for the steady-state and quantum resources of the system
composed of three coupled qubits in the zero temperature limit. Such results
demonstrate that quantum resources between two qubits are strongly affected by
the third qubit in a nontrivial way.
