Physicists produce quantum-entangled images

The natural conclusion: Quantum physics was created by cats (which are sometimes actually turtles).

My dear fellow, it's a wonder your blood pressure is as low as it is. Science is weird, even impossible; except for the fact that the impossible is proven true. Live with it.

Although there's a rumor going around that you actually like giving yourself headaches and strokes with each new quantum development.

[Moriarty]

Actually, the more bizarre the development, the more I grin. It doesn't honestly give me headaches, but somewhere, someone is seriously flipping out. I'm just an amused spectator.

Must have been Schrödinger's cat. ;)

It's not that science is weird, it's that we live in the stone age (i.e. we still have much to learn).

Thanks for the link.

Of course. My comment is subjectively based, telling how things seem to us right now. "Weird" is a very subjective concept to throw around.

This appears to be related to Bell's Theorem, which provides an experimental means of investigating such "action-at-a-distance".

Einstein hated the "action-at-a-distance" idea, and devoted much time to it. He posited a model based upon local hidden variables to handle this. He died in 1955. In 1964, Bell showed that local hidden variables can't explain this away.

Ever since, Einstein has been spinning in his grave... and his angular momentum is quantized.

:laugh:

Ok, I chuckled.

But seriously, what's up with entanglement? Every time I'm fully prepared to dismiss the notion as something simple being completely misunderstood, another case of "Yoohoo! Entangled pair!!!" comes along.

[curiousjane]

Physics. The only science I could fall in love with.

I have downloaded the article. Sometime when I am not at work, doing work things, I will pull it out and let it seduce me.

[ThaiGreenTea]

One of my bane's is physics... Can anyone simplify this article for me? o.O

Light produces mini images or something? Agh.

I can relate to your frustration. I'll give answering your question a shot, but bear in mind that I'm a long way from properly misunderstanding quantum mechanics myself.

Entanglement is a notion that basically says every bit of matter has a "twin". Think of it like the Corsican Brothers: when you step on one twin's foot, the other twin will react. Even though there is no physically apparent connection between the two and they may be separated by miles in some cases, you cannot manipulate one without disturbing the other.

Bizarre enough for you yet?

The photograph is an image that, when properly manipulated by the laser lights in the experiment, "revealed" it's quantum twin.

IBM is pioneering the charge in quantum computing and quantum teleportation, which are applications of this really freaky subset of physics.

What fascinates me most of all is that:

A. Someone had the balls to be the first professional to actually take this seriously. I imagine that was a hard thing to admit to one's scientist friends...

B. They appear to be taking the theoretical models and successfully applying them. In other words, it's actually working, at least so far.

:thinking:

I don't know if it works only between two particles, or whether you can entangle more than two.

Actually quantum entanglement has already been proven in practice and was applied in quantum cryptography.

As for A., there is a guy who is trying to build an experiment proving retrocausality without serious financial support. Most people expect him to fail.

Here are two links about it:

Cool. Thanks.

That's so cool. Makes one wonder what a 'data center' will look like 20-30 years from now. It also sounds like this technology could be used in radiation therapy for cancer patients. To have so much control of the light beam would significantly reduce "collateral damage" done to a patient using today's methods.

Apparently, they can produce these entangled photons.

I should have become a Mech E...they have all the fun.

mechE? do they get quantum fun? go for physical chemistry/physics if you want quantum fun...no, no, I'm not biased at all... :P

QM entanglement fascinates me though. I believe someone I know was researching that. A physical chemist. I want to seriously sit down and read about it for awhile some time when I actually have time. Hmm...I may have access to good books about it here...That's incredible someone got an entangled image though. That's like far more than 2 photons. Interesting. Great article.
