Translational entanglement via collisions: how much quantum information is obtainable?
@article{Tal2005TranslationalEV, title={Translational entanglement via collisions: how much quantum information is obtainable?}, author={Assaf Tal and Gershon Kurizki}, journal={Physical review letters}, year={2005}, volume={94 16}, pages={ 160503 } }
We study collisions mediated by finite-range potentials as a tool for generating translational entanglement between unbound particles or multipartite systems. The general analysis is applied to one-dimensional scattering, where resonances and the initial phase-space distribution are shown to determine the degree of postcollisional entanglement.
