Comment on ``Experimental Nonlocality Proof of Quantum Teleportation and Entanglement Swapping''
Eric Dennis
Abstract
In quant-ph/0201134 Jennewein et al. report experiments demonstrating entanglement swapping under various conditions. In one instance, they claim to have exhibited Bell inequality violations by a pair of photons prior to performing any entangling operations on the pair. However, the Bell inequality violation results in this case from post-selection of the data, not from quantum non-locality.
