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

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.

Today, they have something else to puzzle over. Jay Olson and Timothy Ralph at the University of Queensland in Australia say they've discovered a new type of entanglement that extends, not through space, but through time.

They begin by thinking about a simplified universe consisting of one dimension of space and one of time.

...

What Olson and Ralph show is that entanglement can just as easily work along the y-axis too. In other words, entanglement is so deeply enmeshed in the universe that a measurement in the past has an automatic influence on the future.

1. Entaglements can have serious consequences for sure

[bread_and_roses]

2. Such marvelouos, mind-bending from the physicists -

I just wish I could understand it!

[DCKit]

3. If we understood it, all would unravel.

woooooooooooo!

4. Shall I tell the story about the luggage

that arrived hours before the man checked it in at the airport?

5. I would be more amazed

If a measurement in the future had an automatic influence on the past.

6. If they teleported, does that mean the battle with Gorn did not happen??
