Abstract: We consider a qubit as a working medium in a deformed quantum Otto cycle using Tsallis statistics. To analyze the engine, we obtain the time evolution of the deformed density matrix in different steps of the cycle using the Lindblad equation. We calculate deformed work done, exchange heat, and cycle efficiency. We present a new and exact formula for the dependence of the above parameters with the non-Markovianity of the system, based on mutual information. It finds that the non-Markovian effects can be a resource to extract work from an Otto cycle.
