Manipulation And Non-linear Dynamics Study Of Trapped Ions In Microscopic Surface-Electrode Ion Traps

Quantum information and quantum computation is an important subject generated from the rapidly developed quantum science. Quantum computer has attracted much attention of physicist due to its faster solution of some intractable problems than the classical counterpart. Due to scalability, the microscopic surface-electrode ion trap is a promising device for building future quantum computers, which places the segmen-ted electrodes on the surface of the insulated substrate, forming confinement zones, storage zones and operation zones.This dissertation summerizes the work in the microscopic surface-electrode ion trap, including installation of experimental devices, trapping and control of the ions, the configuration phase transition of the ion crystals and the nonlinear dynamics of the trapped ions. More details are as below.(1) Installation of the microscopic surface-electrode ion trap and accomplishment of the related electronic circuits and laser paths; Observation of the fluorescence from the trapped ions.(2) Realization of Doppler cooling limit and control of the ion crystals (such as splitting, merging and rotating the ions) by adjusting the voltages of the dc electrodes; Study of configuration phase transitions of the ion coulomb crystals, fitted by the method of energy minmization.(3) Research of the Duffing model of the trapped ions in the nonlinear region and the motion transduction of a single-ion between different axes.
