Influence of Various Environments on Information and Entanglement Dynamics for Two Interacting Qubits
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 n...

Zusammenfassung: | 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. |
