en Stationary entanglement and discord for dissipating qubits by local magnetic field تخصصی Special پژوهشي Research We consider a system composed of n non-interacting qubits dissipating into a common environment. A local magnetic field interacting with a qubit is added to generate entanglement between the interacting qubit and each arbitrary qubit, while the system is in the ground state. Our numerical calculations show that turning the local magnetic field off at the maximum entanglement (discord) time, lead to a stationary entanglement (discord) for different system size n.
