文摘

Analytical solutions of the master equation for two interacting qubits in different environments are considered. The qubits are initially prepared in a mixed state. Under the effect of different models of environments, we compare the temporal evolution of atomic quantum Fisher information with the negativity as a measure of entanglement.
