Now that's elegant science. Create one pair of entangled photons, send #1 immediately to a particle/wave detector, send #2 through a 50ms delay to a second detector that can force the state to be particle or wave, and see if you can also force #1 to be one or the other... 50ms before you alter its twin.

Elegant. Simple. Outstanding.

Hmm... I wish I could tell from the article exactly what they were doing...

As it stands it's a bit of a miss-mash...

It seems like they are taking two entangled photons (lets call them Pinky and Brain) and trying to measure an aspect of Pinky's state (and by extention Brains state) 50 ms before they force Brain into a particular state. For this to be interesting, they need a setup for measuring Pinky's state that in isolation would always produce a value A, but because of forcing Brains state produces a value B instead.

They seem to want A and B to be wavelike or particlelike. Maybe I've just not kept up, but all of the entangled parameters I was aware of centered around a conservation law. I don't remember there being a conservation law that would entangle 'wavelike' vs 'particlelike'.

that is the shiznit.
