Title: Entanglement in the dispersive interaction of trapped ions with a quantized field
Author: Semiao, FL
Furuya, K
Abstract: The mode-mode entanglement between trapped ions and cavity fields is investigated in the dispersive regime. We show how a simple initial preparation of Gaussian coherent states and a postselection may be used to generate motional nonlocal mesoscopic states involving ions in different traps. We also present a study of the entanglement induced by dynamical Stark shifts considering a cluster of N trapped ions. In this case, all entanglement is due to the dependence of the Stark shifts on the ions' state of motion manifested as a cross-Kerr interaction between each ion and the field.
