Aufbau eines Experimentes zur Speicherung von Yb+ in einer mikrostrukturierten Paul-Falle

Ions trapped in a Paul trap make an ideal system to investigate quantum mechanical effects. To this end the initial states of the ions are manipulated and fluorescence measurements are used for detection. Such experiments have applications in quantum information processing, in particular in the simulation of quantum systems or the realization of a quantum computer. The Paul trap used to trap ytterbium ions in this thesis is a microstructured segmented trap. Electromagnets are integrated into this trap with which individual ions can be coupled to one another (Magnetic Gradient Induced Coupling - MAGIC) and addressed using microwave radiation. Controlled movement of the trapped ions and adjusting the coupling constant between the ions is possible using the segmented electrode structure. A compact vacuum feed through system is realised using a thick film technique printed onto a ceramic block. More than seventy electric signals are used to control the trap using this feed through. Furthermore, the experiment requires a vacuum chamber and laser sources, all of which were constructed and installed during the course of this work. For the first time a bismuth triborate crystal is used for the generation of laser radiation at 369 nm by frequency doubling. First coherent measurements in the form of Rabi and Ramsey measurements are carried out on the trapped ytterbium ions. Measurement of the energy difference between individual Zeeman levels, allow to determine the ions local magnetic field with a relative uncertainty of one ppm.
