Paper Abstract

Several examples that show the relationship between atomic coherence and entanglement productions have been discussed in this paper. The first example shows how atomic coherence can lead to entanglement between two thermal fields at a temperature T ; In the second example, we demonstrate how a cascade correlated spontaneous emission laser can be used as an entanglement amplifier; The last example illustrates how an arbitrary entangled state of two cavity fields can be prepared through atomic coherence. All these examples seem indicate that the two different quantum effects-coherence and entanglement-are closely related.
