Optimum measurement strategies for trapped ion optical frequency standards

Riis, Erling and Sinclair, Alastair G. (2004) Optimum measurement strategies for trapped ion optical frequency standards. Journal of Physics B: Atomic, Molecular and Optical Physics, 37 (24). pp. 4719-4732. ISSN 0953-4075

The experimental parameters required in order to maximize the stability of a single-ion based optical clock are analysed. This stability is a trade-off between on the one hand the steepness of the discriminant signal derived from the laser excitation of the ion and on the other the binomial noise associated with the excitation of a single particle. Optimum conditions are found for both Rabi and Ramsey excitation of the clock transition.
