Abstract

The entanglement dynamics of three trapped ion interacting with red sideband tuned single mode of a cavity field is examined. Analytical expressions for the state of three ions and the cavity field are used to obtain the global, four-way, three-way and two-way negativities. For the cavity field initially prepared in a number state, the probability of generating three ion W-state is calculated. Analytical expressions for K-way entanglement measures (K=2 to 4) are obtained and plotted as a function of time.
