Entanglement generation via scattering of two particles with hard-core
repulsion
Frank Schmüser, Dominik Janzing
abstract: We analyse the entanglement generation in a one dimensional scattering
process. The two colliding particles have a Gaussian wave function and interact
by hard--core repulsion.In our analysis results on the entanglement of two mode
Gaussian states are used. The produced entanglement depends in a non-obvious
way on the parameters ratio of masses and initial widths. The asymptotic
wavefunction of the two particles and its associated ellipse yield additional
geometric insight into these conditions. The difference to the quantitative
analysis of the amount of entanglement generated by beam splitters with
squeezed light is discussed.
