Dynamics of pairwise entanglement between two Tavis–Cummings atoms
Jin‐Liang Guo, He‐Shan Song · Journal of Physics A Mathematical and Theoretical · 2008
We investigate the time evolution of pairwise entanglement between two Tavis–Cummings atoms for various entangled initial states, including pure and mixed states. We find that the phenomenon of entanglement sudden death behaviors is distinct in the evolution of entanglement for different initial states. What deserves mentioning here is that the initial portion of the excited state in the initial state is responsible for the sudden death of entanglement, and the degree of this effect also depends on the initial states.
