  We address the dynamics of quantum correlations in a two-qubit system subject
to unbalanced random telegraph noise (RTN) and discuss in details the
similarities and the differences with the balanced case. We also evaluate
quantum non-Markovianity of the dynamical map. Finally, we discuss the effects
of unbalanced RTN on teleportation, showing that noise imbalance mitigates
decoherence and preserves teleportation fidelity.
