Decoherence sensing of even and odd coherent states via unambiguous quantum state Filtering
Gui-Lian Zhang · Journal of Hunan University of Science and Engineering · 2006
In this paper, we apply unambiguous quantum state filtering to evaluation of the sensing decoherence channel for odd and even coherent probe states. We find that odd coherent probe showed better performance than even coherent probe. We also find that the asymptotic behavior of the precision limit is the same as that of other probe fields.
