Delocalized Entanglement of Atoms in optical Lattices
arXiv:quant-ph/0611132 · doi:10.1103/PhysRevLett.98.190502
Abstract
We show how to detect and quantify entanglement of atoms in optical lattices in terms of correlations functions of the momentum distribution. These distributions can be measured directly in the experiments. We introduce two kinds of entanglement measures related to the position and the spin of the atoms.
