dc.description.abstract | The optimal precision of frequency measurements in the presence of decoherence is discussed. We analyse different preparations of n two-level systems as well as different measurements procedures. We show that standard Ramsey spec- troscopy on uncorrelated atoms and optimal measurements on maximally entangled states provide the same resolution. The best resolution is achieved using partially entangled preparations with a high degree of symmetry. | en |
