| Popis: | In this paper we offer a new surface trap design capable of coupling the ion motion in the selected wells among ten by adjusting the DC-voltages on a set of electrodes. We demonstrate and characterize a variety of phonon mode spectra for different voltage sets for 10 ion-architecture for two types of ions Ca and Be. We found that it is possible to unite the ions into segments with unique phonon mode frequencies to perform parallel MS-gate operations. We also model the fidelity of the MS-gate operation for a segment comprise of two ions accounting the two main contributions to the gate infidelity: the limited frequency difference between phonon frequencies of the segments and the finite drift of the phonon frequencies expected in experiment. Additionally, we investigate how the number of ions per individual trap and an anharmonic potential terms affect the coupling between the two wells. Comment: 11 pages, 9 figures |
