>>12629238yes, it was a very clever experiment, but it was fucked up cause the 3 results were back-targets with
super-position
2 band-pattern
decoherence
the delayed choice showed it was possible to sample the entangled photon without becoming un-entangled with its copy...
if it was un-entangled with its copy then we would of seen another double-bar pattern (but we didn't)..
but what we saw was a decoherence pattern that was more likely to of been a result of the two photons having a different travel-path length so the target-pattern was subject to uneven construction & interference patterns.
they should of varied the path of the delayed choice to make its length greater, equal to and then less than (3 experiments), so as to show if decoherence of entanglement had occurred or if they were still entangled but the different travel-lengths made an uneven non-perfect super-positon pattern.
