    "abstract": "We present a theoretical study of the relationship between entanglement and\nentropy in multi-qubit quantum optical systems. Specifically we investigate\nquantitative relations between the concurrence and linear entropy for a\ntwo-qubit mixed system, implemented as two two-level atoms interacting with a\nsingle-mode cavity field. The dynamical evolutions of the entanglement and\nentropy, are controlled via time-dependent cavity-atom couplings. Our\ntheoretical findings lead us to propose an alternative measure of entanglement,\nwhich could be used to develop a much needed correlation measure for more\ngeneral multi-partite quantum systems.",
