Mesoscopic quantum superpositions in bimodal Bose-Einstein condensates: decoherence and strategies to counteract it
Krzysztof Pawlowski, Matteo Fadel, Philipp Treutlein +2
We study theoretically the interaction-induced generation of mesoscopic coherent spin state superpositions (small cat states) from an initial coherent spin state in bimodal Bose-Ei…

Spin squeezing and EPR entanglement of two bimodal condensates in state-dependent potentials
Hadrien Kurkjian, Krzysztof Pawlowski, Philipp Treutlein +1
We propose and analyze a scheme to entangle the collective spin states of two spatially separated bimodal Bose-Einstein condensates. Using a four-mode approximation for the atomic…
