Tīmeklisμ l is the Lamb-Dicke parameter of the trapped atomic l-ion. Based on the procedure described for engineering N two-level cold ions beyond the Lamb-Dicke limit [ 35 , 54 , 55 ], we consider the case where the two-level cold ions (two-qubit system) are closed to each other, and the total center of motion of them is the center-of-mass vibration ...

However, typical … TīmeklisIn this study, our goal is to obtain the entanglement dynamics of trapped three-level ion interaction two laser beams in beyond Lamb-Dicke parameters. Three values of LDP, η=0.09, η=0.2 and η=0.3 are given. We used the concurrence and the negativity to measure the amount of quantum entanglement created in the system.
