An optimized qubit for the next generation of quantum information: The A = 133 isotope of barium
Abstract
This experimental effort seeks to develop trapped barium-133 ions ( 133Ba+ ,a man-made radioisotope) for an all-purpose, optimized qubit with unique properties not found in any naturally occurring species. The radioactivity of this isotope is a complication that can be dealt with in a way that is compatible with existing trapped ion quantum information processors, and is justified by the advantages of this species over the other ions in use. This effort seeks to experimentally develop techniques to load and cool 133Ba+, as well as perform state initialization, qubit operations, and state detection. Specifically this effort will construct and test a linear Paul trap for 133Ba+ and apply laser cooling in order to make the first-ever measurement of the hyperfine structure and demonstrate the qubit clock state with a fidelity greater than 98%.
