Abstract

In this work, the quantum entanglement and quantum linearity in a trapped ion-phonon system are theoretically explained in terms of the second-order terms of the Lamb-Dicke parameter, eta. For the trapped ion-phonon system, the optimum times are 2 and 10 and the optimum probability amplitudes of ions are 0.4 and 0.58, respectively. With the optimum times and amplitudes, it is shown that as eta grows, the quality of the entanglement in the trapped ion-phonon system increases. In particular, we have demonstrated the quantum linearity due to second-order terms of eta.
