Abstract
In this communication we discuss different aspects of information entropy and its application as an indicator of the quantum entanglement. We focus on the dynamics of multi-atom systems coupled to a nanomechanical resonator under influence of both a phonon bath in contact with the resonator and irreversible decay of the qubits. Even in the presence of enviroment, the inherent entanglement is found to be rather robust. Due to this fact, together with control of system parameters, the system may therefore be especially suited for quantum computer. Our findings also shed light on the evolution of open quantum many-body systems.
