Decoherence and quantum error correction in frequency standards
The precision of frequency measurements performed on trapped ions in the presence of decoherence is analysed. In particular, standard Ramsey spectroscopy on uncorrelated ions and optimal measurements on maximally entangled states are proved to lead to the same resolution, while the best precision is...
