Query: Optical Control of a Quantum Rotor   The possibility to coherently control a quantum rotor is investigated
theoretically. The rotor is realized by an antiferromagnetic spin-1
Bose-Einstein condensate, trapped in the optical field of a Fabry-Perot
resonator. By tuning the pumping field of the resonator, coherent control over
the rotor is achieved. The technique is illustrated by the numerical simulation
of a protocol that transforms the rotor's ground state into a squeezed state.
The detection of the squeezed state via measurement of intensity-correlations
of the cavity field is proposed.
