patchouli has it right - he's given a MUCH better explanation of quantum entanglement than the dumb article does. And he did it very succinctly.

The upshot is, it doesn't matter how far apart the entangled particles are, the quantum state gets "broadcast" from one particle to the other instantaneously. One particle could be in a different galaxy on the other side of the universe and you could transmit the data instantly. It's amazing stuff.

Not possible, but even if it was, one small error and your screwed. See the movie "The Fly".


That's what I was thinking!

quantum tunneling

Star Trek has it covered. They called that 'subspace jumps'. Same thing. But you can't do it 'cause it damages your dna every time you jump.

I love the idea of entanglement because firstly it breaks huge numbers of our current physical laws as we view them, and secondly because it introduces the idea of instant communication between any points in the universe which beats the crap out of radio.

This is not teleportation. This is closer to radio than it is teleportation. Basically (VERY basically), there are two particles. Neither choose a charge (negative or positive) until one of them does. If the first particle becomes positive then the second will become negative and visa versa. The cool thing is, they can be miles apart (one could be on Earth and the other could be on the moon, for example) and it would still work. This then becomes a very fast way to transmit a state (negative or positive) over a far distance. If you assign a zero to one state and a one to the other, you get information being transfered.

Also, with teleportation, you would need to destroy yourself and have a perfect clone of you made on the other side. You would die but another you would go on. So I don't see teleporting - a la Star Trek - as being all that popular.

Not sure if this is true. You'll have to run it by the I-A-B viewers first.

This article is idiotic.
When it talks about "teleportation" it is in actuality referring to quantum tunneling which is an entirely different event.

And the way it explains qubits is ludicrous.

I hate when someone tries to "dumb down" an explanation of a scientific process because all you end up with is pure "dumb".

If you want to understand something then study it and become knowledgeable on the subject.
Idiocy like this leads to people having unreal expectations of science which leads to distrust and belief in unfounded myths.

Trud,
"It violates the laws of quantum mechanics"

You presume we will not know more, or have new physics by then. Think about the difference 100 years makes. It's been done on a small scale. It is possible on a large scale. Just need more time & knowledge.

To be more specific than saying that teleportation is not possible with destroying the original...

There is a scientific law called Heisenberg's uncertainty principle. Star trek dealt with this by making up the "Heisenberg compensator".

It works like this...The human brain and consciousness takes place on the smallest of levels. Particles that small cannot be measured without changing the particle itself. That is the uncertainty principle. You cannot know where a particle that small is, AND what is doing.

To transport someones body and conciousness, you would have to precisely measure the particles that make that person up. The act of measuring would destroy the person.

Quantum mechanics is the most successful branch of science ever created. There is almost zero chance that the uncertainty principle will ever be violated.

Teleportation is not possible in the star trek sense. There could be a copy of you created at another location, but the original copy would be destroyed in the process. It violates the laws of quantum mechanics.

"Why can't the option of teleportation and we still know who we are just mean that we are data that's transferable?"

I agree with that. I just posed the question. It's good to exercise your grey matter with some intellectual debate.

@Gerry

Why can't the option of teleportation and we still know who we are just mean that we are data that's transferable? A better question and conundrum I find is the person coming out of the teleport the same person?

Because in order to teleport you are killed, and rebuilt. Technically you are dying and being reformed elsewhere. Chew on that.

Star Trek - it's all becoming real...eventually.
But it does pose a philosophical question: Does your soul transport? If there is such a thing as a soul, can a machine take it apart & rebuild it in a different location? If it could it would be measurable so that could provide conclusive proof of souls... so is that conclusive proof of a creator of souls?

If you have a soul, but a machine cannot rebuild it, would it leave you a soulless zombie on the other side?

Would you ride a transporter beam?

Talk amongst yourselves on that one.
