As. Parkins et al., SYNTHESIS OF ARBITRARY QUANTUM STATES VIA ADIABATIC TRANSFER OF ZEEMAN COHERENCE, Physical review letters, 71(19), 1993, pp. 3095-3098
A scheme for the preparation of general coherent superpositions of pho
ton-number states is proposed. By strongly coupling an atom to a cavit
y field, atomic ground-state Zeeman coherence can be transferred by (c
oherent) adiabatic passage to the cavity mode and a general field stat
e can be generated without atomic projection noise.
