Entanglement generation by collisions of quantum solitons in the Born approximation

Maciej Lewenstein1,2 and Boris A Malomed3

Show affiliations


We present analytical expressions describing the generation of entanglement in collisions of initially uncorrelated quantum solitons. The results, obtained by means of the Born approximation (for fast solitons), are valid for both integrable and non-integrable quasi-one-dimensional systems supporting soliton states.
