Calculation of the quantum discord in many-qubit systems    [PDF]

A. Y. Chernyavskiy, S. I. Doronin, E. B. Fel'dman

For the first time, we compute the quantum discord in bipartite systems containing up to nine qubits. An analytical expression is obtained for the discord in a bipartite system with three qubits. The dependence of the discord on the temperature and the structural parameter of the model is studied.
