文摘
Master equation for two interacting qubits coupled to a thermal bath derived. Equation analytically solved without the RWA. Evolution of Concurrence, Discord and Linear Entropy for different temperatures. Results compared to an ad hoc model. Inadequacy of the ad hoc model even in weak coupling regime.
