As far as I know, quantum entanglement has not been validated yet, as all experiments since Alain Aspect's 1982 paper suffer from flaws in experiment design, leading to what is known as "loopholes".

Wuh...? Care to cite a source for that?

I do believe there have been experiments that have successfully transmitted data via quantum entanglement.

I don't really feel like digging up a source at the moment though.

Wait, what? Instantaneously?

No data is ever transmitted via quantum entanglement (at least, data from the perspective of the observer). Entanglement is simply when two particles exist in the same quantum state. (Or, to be more precise, in the same superposition of quantum states.) When the state is observed (say, an experimenter examines one of the particles), then the entire wavefunction collapses to a single quantum state. The two particles in the system therefore collapse to the same state instantaneously, but no information can ever be transmitted in this way.

My understanding is quite limited, but I've believed this to be truth. Anyone know anything about this?

You're citing an article from 1982?

There's been a massive amount experimental work done since the mid 1990s.

I said experiments since that landmark 1982 paper...

AFAICT, quantum entanglement is a blanket term for unexplained magic. It would be "real" if they could use this "magic" to construct something that otherwise can't be explained by anything else.

Is there proof of anything constructive coming out of quantum entanglement?

teilo4• 16 years ago

Then I guess you can't tell very far.

I think you are confusing measurable, reproducible quantum entanglement with the quackish invocation of the term to lend scientific credence to kooky paranormal theories.

There's a reason that Einstein was freaked out by "spooky action at a distance" and it wasn't because it didn't exist. It's because it did.

Have you measured quantum entanglement? I'm trying to.

... and in other news, pigs have grown wings and are flying!

seriously, why QE? is base stacking plus some electron cloud sharing not a good enough explanation for dsDNA?

will the anonymous downvoter please stand up and show some gumption?
