Entanglement and generation of superpositions of atomic coherent states
J. Récamier, Octavio Castaños, Rocío Jáuregui, Alejandro Frank · Physical Review A · 2000
After making a general description of the properties of macroscopic superpositions of collective atomic states, we present a detailed analysis of a method for their experimental realization recently proposed by C.C. Gerry and R. Grobe [Phys. Rev. A 56, 2390 (1997)] which is based on cavity QED techniques involving the manipulation of electromagnetic and matter fields. Specific conditions and limitations of the procedure are discussed.
