Physical Review A, 70(5), Article 053813. https://doi.org/10.1103/PhysRevA.70.053813http://hdl.handle.net/20.500.14446/19732We propose the cavity quantum electrodynamics method, using dispersive interaction between atoms and a high-quality cavity to realize the mesoscopic superposition of coherent states that would exhibit sub-Planck structures in phase space, i.e., the structures at a scale smaller than the Plank's constant (h-bar). These structures are direct signatures of quantum coherence and are formed as a result of interference between the two superposed cat states. In particular we focus on a superposition involving four coherent states. We show interferences in the conditional measurements involving two atoms.application/pdfThis material has been previously published.
