It is my limited understanding that the idea of "a different photon" would be sort of irrelevant here as quantum state is the only thing that differentiates objects such as photons from one another. Outside of that, photons are essentially fungible. I don't really understand the finer points of the experiment however and I could be totally wrong in my understanding.

- knodi123 12y agoI can imagine a world where they're more than just fungible- They could even be literally the same object. See http://en.wikipedia.org/wiki/One-electron_universe http://en.wikipedia.org/wiki/One-electron_universe
