  We explore the quantum correlations, fidelity and quantum thermodynamics of
two coupled double quantum dots containing two excess electrons. In this
regard, we investigate and compare the evolution of those measures under
thermal effects and tunneling coupling. We find the hierarchy of quantum
correlations, and one-way steering between the two quantum dots. We found, as
expect that the quantum correlations are diminishes by increasing the values of
temperature. We show that this state can be used for quantum teleportation. On
the other, we address the extracting work and efficiency of the state. We
compare the extraction work with the bare energies. Our results show that
quantum dots states have a reliable and better capacity to preserve quantum
correlations and remain one of the good resources for the deployment of quantum
information processing protocols.
