and the idea proposed by Asher Peres: http://arxiv.org/abs/quant-ph/9904042

is it possible to have delayed choice multi-entanglement swapping? i.e. create four pairs of photons – 1+2, 3+4, 5+6 and 7+8. Measure photons 1 and 8 first, then swap entanglement between the remaining six photons. I.e. bell-state measure photons 2 and 3, then bell-state measure photons 4 and 5. Then bell-state measure 6 and 7. I hope that made sense. I’m thinking the details out in my head.

Would that, in the end, make photons 1 and 8 entangled? If not, what scheme similar to the above would?

Many thanks
