Abstract: We are setting up to do basic quantum logic operations with trapped Ba ions at the University of Washington. I will describe our recent progress which includes: single qubit preparation, manipulation and detection; ultrafast pulsed laser excitation of single ions for ion-photon entanglement demonstration; a very high-N.A. optical system for efficient collection of single ion fluorescence; and coupling of such fluorescence into a single-mode optical fiber. Our future plans include entanglement of two Ba ions over long (~ 1 km) distance and the development of ultrafast quantum logic gates between small sets of ions.
