New Type Of Entanglement Allows "Teleportation in Time", Say Physicists

Posted January 17, 2011 8:17 AM

From Technology Review RSS Feeds:

Entanglement is the strange quantum phenomenon in which two or more particles become so deeply linked that they share the same existence. That leads to some counterintuitive effects, in particular, when two entangled particles become widely separated. When that happens, a measurement on one immediately influences the other, regardless of the distance between them. This "spooky-action-at-a-distance" has profound implications about the nature of reality but a clear understanding of it still eludes physicists.

Sorry. The whole article sounds much like the "closing line".

"That isn't clear. Neither is it clear exactly how such an experiment might be done although."

An earlier line: "But how is this different from ordinary existence? After all, we're all time travellers, moving into the future at the same rate" says it all.

Somebody please explain (this) :

Fundamentally-speaking, when we "take-a-measurement" on something at the 'quantum-level' , we cause a change in that "something", by virtue of having observed it , yes?

So: here are 2 entangled "somethings". We "know" they are entagled because when we "measure" them, they are in the same state. If we change the state of one (and we *know* it is changed because we measured the change)... we "prove" the state-of-entanglement by "measuring" the change on the other-something.

WAIT! "No!!!!" Don't take a measurement, cuz that'll change it!

Really : I *DO* like the idea , the concept of entanglement.

I just wish somebody would use real, honest-to-goodness English sentences, in their entireties, without "fluff", "dreams", rhetoric, etcetera , in order to explain it.

Or ... is this actually one of those "Hollywood" type concepts that can only be understood by someone who hasn't mastered (their own) language?

< sigh >
