    "abstract": "The stability of entanglement of two atoms in a cavity is analyzed in this\nwork. By studying the general Werner states we clarify the role of Bell-singlet\nstate in the problem of suppression of disentanglement due to spontaneous\nemission. It is also shown explicitly that the final amount of entanglement\ndepends on the initial ingredients of the Bell-singlet state.",
