We consider locally thermal states (for two qubits) with certain amount ofquantum entanglement present between them. Unlike previous protocols we showhow work can be extracted by performing local unitary operations on this stateby allowing those two qubits to interact with thermal baths of differenttemperatures, thereby gradually removing the entanglement between them tillthey reach a direct product state. Also we demonstrate that, further work canbe extracted from this direct product state by performing global unitaryoperation, thereby establishing that work can be extracted from a systemcomposed of locally thermal subsystems even after removing quantum correlationsbetween them if the subsystems are thermalized at different temperatures. Alsowe show that even if we consider a initial state where there is no entanglementbetween the two qubits, we can also extract work locally using our method.
