I seriously had to read this three times.

Quantum Experiment Shows Effect Before Cause

Quote from: 'steveb3210 writes'
"Physicists have demonstrated that making a decision about whether or not to entangle two photons can be made after you've already measured the states of the photons."

Here's the article's description of the experiment:

'Two independent sources (labeled I and II) produce pairs of photons such that their polarization states are entangled.

One photon from I goes to Alice, while one photon from II is sent to Bob.

The second photon from each source goes to Victor.

Alice and Bob independently perform polarization measurements; no communication passes between them during the experiment—they set the orientation of their polarization filters without knowing what the other is doing.

At some time after Alice and Bob perform their measurements, Victor makes a choice (the "delayed choice" in the name). He either allows his two photons from I and II to travel on without doing anything, or he combines them so that their polarization states are entangled.

A final measurement determines the polarization state of those two photons.


... Ma et al. found to a high degree of confidence that when Victor selected entanglement, Alice and Bob found correlated photon polarizations. This didn't happen when Victor left the photons alone.'

The state of the photons turns out to be the state measured by the guy who did the measurements AFTER the fact, but without prior knowledge of what those states were?

My eyes are trying to invertthemsels into my skull.

Trying to comprehend this is like trying to visualize a floor tiled with regular octagons.

Seriously?  Dang, you guys just don't have any sense of faith at all, do you?  It's easy.  The photons know what's going to happen, so they adjust themselves accordingly.  Then Santa gets diabeetus, and Christmas gets cancelled.  It's simple!

Sure. But the thing is is that my brain is screaming "BUT FUCKING HOW?!?!?!"

I mean, times supposed to be linear, right? I think I read about other experiments, recently, that suggested it was impossible to affect the past. Though, that said, it may have involved particles not on the quantum level.

I gave up the science thing in favor of the music thing 18 years ago (I blame Crazy Uncle Bob for exposing me to Nirvana). I need QUANTUM dumbed down into Guitarist.

Also, it just humorously occurred to me that Crazy Uncle Bob is perhaps the most influential person in my life. since he sparked a major career goal shift.

I'm not sure how I feel about that. I call him Crazy Uncle Bob for a reason, since I only have one uncle named Bob (the other uncle Robert goes by Rob, and is my grandmother's brother).
