Preparation of superpositions of coherent states of a field via the Raman interaction
Shi-Biao Zheng, Guang‐Can Guo · Quantum and Semiclassical Optics Journal of the European Optical Society Part B · 1997
A method is presented for generating superpositions of coherent states of a cavity field via the atom - cavity-field Raman interaction. After an atom has interacted with a cavity field, initially in a coherent state, it is detected through the Raman coupling. Then the cavity field collapses into a Schrödinger cat state.
