A -- Quantum Logic for Trapped-Ion Optical Clocks

The National Institute of Standards and Technology (NIST) proposes to negotiate on a sole source basis with the University of Colorado - Boulder, Physics Department (Dr. Neil Ashby, PI) to carry out experiments on trapped-ion optical clocks that incorporate elementary quantum information processing. *** Over the past few years, NIST has initiated a program in quantum information processing. The Ion Storage Group of the Time and Frequency Divison has demonstrated all of the basic elements of quantum computation with the system of trapped atomic ions. During the course of this work, other applications of quantum information processing have emerged. In particular, using the basic elements of quantum logic, it should be possible to realize an atomic clock with performance surpassing that of any existing atomic clock. Based upon close contacts with all groups in the world that perform this type of work, the Ion Storage Group believes that Dr. Ashby and his colleagues are unique in possessing the required skills in both trapped-ion quantum information processing and laser stabilization. Further, the NIST facilities in Boulder are world-class and could not be duplicated elsewhere in a reasonable time or at a reasonable cost. *** Work will include the following tasks: (1) Construct and set up ion trap apparatus for the simultaneous storage of A1+ and Be+ ions; (2) build dye laser system for 626 nm light; (3) Build frequency doubler to convert 626 nm light to 313 nm for cooling/detection of Be+ ions; (4) perform laser cooling experiments that use a single Be+ ion to sympathetically cool a simultaneously stored A1+ ion; (5) set up CW dye laser at 534 nm and frequency lock to existing stable reference cavities; and (6) set up frequency doubling system to convert 534 nm light to 267 nm. *** This small purchase acquisition (NTE $100K) is being conducted under the authority of FAR Part 13.1.
