Extracting work from multiqubit-interacting system coupled to a common environment

Abstract

We consider the task of extracting work from multiqubit-interaction system coupled to a common non-Markovian environment. By adjusting various parameters such as the number of qubits and the strength of interaction between qubits, the environment can be made non-Markovian in both strong coupling and weak coupling states. It will be shown that the number of qubits and the coupling strengthbetween the qubits have a positive role for enhancing the process of extracting work from the quantum system.
