1) 'Pulling them' using different techniques. E.g. if the particles are charged you can use magnetic fields. Using magnetic fields is as you move particles at the LHC.

 

2) Nobody is transporting a particle at the end of the universe, whatever what you mean by "end". Transporting material to the opposite part of the Earth is not so difficult, but I suspect that you refer to some statement in some book where the author is really trying to explain that entanglement is independent of the distance.

How would they transport material to the opposite part of the Earth?

Yes. I've read that entanglement is independent of distance. Is this a fact or a theory?

2) The experiment war really done. By Alain Aspect, at Orsay University, less than three decades ago.

 

The observation is that not only do the states of both particles match: they do it so quickly that even light would not have enough time to propagate from one detector to the other to tell the other detector what it shall do.

 

This was a serious interrogation (Einstein, Podolsky and Rosen called it a "paradox" then), because Relativity supposes that no information can propagate faster than light does. If we could exchange information without delay, compare clocks and rulers instantly, then Relativity couldn't claim "A sees B's clock go slower, and B sees A's clock go slower as well, and this is normal". This situation would become imposible, and Relativity would collapse.

 

The (most common) interpretation of Aspect's observations (repeated many times meanwhile) is that the entangled pair of particles "decides" in which state it is. The rest of the world, and notably the observers, can't decide the state of a detected particle. So entangled particles are not a means to transmit information, hence their too fast behaviour doesn't ruin Relativity.

So, entanglement and its purpose remain a mystery—yes?

Hello to all:

I'm a fine artist, writer, and kiteflier of some note.

In my book, An Artist Empowered, I included a chapter on Art & Physics. There are many parallels between the two.

I'm writing a novel that takes place in an alternate universe that includes practical applications (fiction for now) of quantum physics.

Entanglement:

1) How do physicists physically separate two particles?

2) When we read that when one particle is observed it will instantly mirror its partner on opposite ends of the Earth or the universe, how would they transsport that particle to that far distant location?

I would appreciate a reply in more layman's terms.

Thanks.
