Teleportation exists :O

How did I miss this last year?

I don't get it. 'Schrödinger's cat' experiment does not require the cat to be alive or dead, it just postulates that it can be one way or the other and we don't know unless we check.

How can we use this to move data where we require it to be in an existent state, not a "we dont know if it exists or not" state, or am I just not getting this at all.

That stainless steel bed must've cost hundreds of thousands of dollars.

That's an optical table. It's supported on pneumatic dampers to eliminate vibrations.

They're expensive, but not actually THAT expensive. Tens of thousands, not hundreds.

Nope, that's not it at all. The cat is BOTH alive AND dead, and it's only when you make the observation that you collapse the waveform and one of the states becomes true.

Here is an article that explains it a little more, but still sorta beats around the bush when it comes to exactly what superposition has to do with it.

That is how I can both work, and not work, at the same time. Until someone observes me the waveform function remains unresolved.
 
I don't agree with these thought experiments. Whether or not I've observed that the cat is dead or alive is irrelevant. The cat's either dead or alive. It's not both purely based on the fact that I haven't observed it one way or the other. Relative to me, I may not be able to PROVE one way or the other, but relative to the box, the box knows whether the cat's dead or alive. But that doesn't mean that the cat is BOTH dead or a live.

Also, wouldn't the teleportation of light imply that the light is traveling faster than light?

It's an analogy. A quantum cat (not a real macro-scale cat) truly is in both states at once. It's not a question of what you agree with or believe, it's scientific truth, well documented and worked out.

Many seemingly impossible things are possible with quantum mechanics.

Sure, I understand the fact that certain quantum states are possible simultaneously, and that the act of observing those states causes them to change.

However, the "analogy" sucks a big one.
 
I don't read up much on quantum computing and the theories much. But based on what I read, would this eventually lead to lag/latency free communication?

You seem to have completely missed the point.

Literalists tend not to do very well in science.

I agree, but then again most analogies suck. They are usually just used to try and make someone understand a point. I don't like that one at all, it just adds confusion.

How thick is that table? Are there not thousands of tapped holes in it?

EDIT: I see after reading the Wikipedia entry that the table is not solid. That would explain the lesser cost. To flatten a thick plate of stainless steel to the appropriate tolerance, and drill&tap all those holes is really a fortune, though.

the funny thing is the definition of "observing" ..
