A fat Schrödinger's cat of Rydberg dressed atomic clouds — Sebastian Möbius, Michael Genkin, Alexander Eisfeld, •Sebastian Wüster, and Jan-Michael Rost — Max Planck Institute for the Physics of Complex Systems, Nöthnitzer Strasse 38, 01187 Dresden, Germany
We propose Schrödinger's cat-states of hundreds of atoms, in a spatial superposition of locations micrometers apart, which would come closer to the original than even the impressive recent experimental progress, e.g. .
In Rydberg dressed ultra-cold gases, ground state atoms inherit properties of the admixed Rydberg state, such as long-range hyperfine state-dependent interactions [2-4]. We present an idea, how a pair of atomic clouds can evolve into a spatial Schrödinger's cat state under the influence of these interactions. The two clouds, containing about 50-100 atoms each, are then in a coherent superposition of two discrete locations, separated by micrometers. The same interactions responsible for this spatial state, can also be exploited to create the initially required entanglement in hyperfine space.
