Abstract

We study the creation of polarisation entanglement by means of optical entanglement swapping (Zukowski et al., [Phys. Rev. Lett. 71, 4287 (1993)]). We show that this protocol does not allow the creation of maximal ‘event-ready’ entanglement. Furthermore, we calculate the outgoing state of the swapping protocol and stress the fundamental physical difference between states in a Hilbert space and in a Fock space. Methods suggested to enhance the entanglement in the outgoing state as given by Braunstein and Kimble [Nature 394, 840 (1998)] generally fail.
