| 英文摘要 | This thesis describes theoretical and experimental work for 40Ca+ ion trapping, aiming at trapped ion quantum computer and quantum information processing. The foreword briefly reviews the development history of ion trapping and its research significance. The second chapter describes the theory of ion trapping and its development, and its application in quantum information and quantum computation, describes the requirement and calculation of ion trap quantum computer. The third chapter analyzes a design of surface ion chip, and compares it to the typical linear Paul trap. Then the distribution of its electric potential by using static electric field is calculated through finite element analysis method. The applicability and advantage of the configuration are described. The fourth chapter introduces a planar ion chip design with a two-dimensional array of linear ion traps for a scalable quantum information processor. The potential distributions are calculated using static electric field qualitatively. This architecture is conceptually simple and many current microfabrication techniques are feasible for the basic ion chip structure. The fifth chapter presents a three-dimensional scalable linear ion trap scheme for ion trapping and discuss its applications for the optical frequency standard and scalable quantum information processing with its parallel strings of trapped 40Ca+ ions. The sixth chapter introduces the experimental design of a typical linear ion trap system. In the experiment 40Ca+ ions would be trapped and cooled in a linear trap design firstly, then a three-dimensional 3*3 rods design would be utilized to trap ions. Furthermore, the above discussed planar ion chips can be fabricated and installed experimentally. Meanwhile, the experimental equipment is described, including the design of the ion trap, the design of the ultra high vacuum system, the laser system, and brief computer control system. Finally, the last chapter is the conclusion of the thesis, the oncoming research, and the prospects in our lab. |
