- Abstract: Considering the unique energy level structure of the one-axis twisting
Hamiltonian in combination with standard rotations, we propose the
implementation of a rapid adiabatic passage scheme on the Dicke state basis.
The method permits to drive Dicke states of the many-atom system into entangled
states with maximum quantum Fisher information. The designed states allow to
overcome the classical limit of phase sensitivity in quantum metrology and
sensing. We show how to generate superpositions of Dicke states, which maximize
metrological gain for a Ramsey interferometric measurement. The proposed scheme
is remarkably robust to variations of the driving field and the number of
atoms.
