Quantum entanglement in spinor Bose-Einstein condensates
L. -M. Duan, J. I. Cirac, P. Zoller
We propose a scheme to generate and detect various kinds of quantum entanglement in a spin-1 Bose-Einstein condensate. It is shown that substantial many-particle entanglement can b…
Separability Criterion for all bipartite Gaussian States
G. Giedke, B. Kraus, M. Lewenstein +1
We provide a necessary and sufficient condition for separability of Gaussian states of bipartite systems of arbitrarily many modes. The condition provides an operational criterion…
Distillability Criterion for all Bipartite Gaussian States
G. Giedke, L. -M. Duan, J. I. Cirac +1
We prove that all inseparable Gaussian states of two modes can be distilled into maximally entangled pure states by local operations. Using this result we show that a bipartite Gau…
Squeezing and entanglement of atomic beams
L. -M. Duan, A. Sørensen, J. I. Cirac +1
We propose and analyze a scheme for generating entangled atomic beams out of a Bose-Einstein condensate using spin-exchanging collisions. In particular, we show how to create both…
