Abstract

We consider two non interacting two-atoms Tavis -Cummings systems and examine the entanglement among four two-state atoms. For our purpose, we assume that one atom fro m each system are entangled init ially and we obtain time-dependent concurrence among atoms. There are six pairwise concurrences among atoms and in this paper, we focus on remote atoms . We show that initially non-entangled atoms 2 A and 2 B becomes entangled by passing time, the process
