Abstract
In this section we aim to generalize the entanglement swapping procedure to continuous variable systems and show that for certain types of pure continuous variable states this process can increase the amount of entanglement between separated parties i.e. achieve entanglement purification. To show this we will need a generalization of the von Neumann entropy — the finite state entanglement measure — to continuous variables together with a numerical procedure for its calculation.
