Kamog, Quantum mechanics holds that a beam of light, even laser light, exhibits small energy irregularities (shot noise) owing to the effects of vacuum fluctuations (electromagnetic fields in the vacuum whose omnipresence is sanctioned by Heisenberg's uncertainty principle). Over the past ten years physicists have been able partially to overcome this problem by reducing the noise in either the phase or the amplitude of the light at the expense of the other. The resultant "squeezed light." Does that cover it? I can give you a summary of Heisenberg's uncertainty principle. If you need.
As to how entanglement work? I am assuming you are referring to "Quantum Entanglement." Yes?
Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. OK?

Kamog, phyisist are confused by physic. More particularly Quantum Mechanics. So, don't be discouraged. As you stated,

Quote:

"I figure that if I keep learning about quantum mechanics I'd eventually figure it out."

Just keep learning!

Hope that helped, a little.

Thanks for the explaination! Yes, that helps.

I only took a third-year quantum mechanics course in university, and mostly what we did in that course was to study electrons trapped in different kinds of quantum wells, solving the Schrodinger equation for these simple cases and for the hydrogen atom. We also learned about the Heisenberg uncertainty principle, de Broglie wavelengths, wave-particle duality, the energy of photons, tunneling and so on. But we didn't learn anything about quantum entanglement or quantum teleportation!

I am glad to hear, it helped!

I've seen bumper stickers that say, "Heisenberg may have slept here."

capnq, I've seen those, too. Your post reminded me of, the first time I did. I was at Berkley, in a parking lot. I did find myself smiling with the thought of Heisenberg blanching precariously on that bumper. Anyway as I got closer to this car, I could see there was other writing on the bumper sticker. I got to the car, it read; " so did Copernicus, Euclid, Pascal and that other FAMOUS mathematician guy, AH Einstein!". I almost hurt myself LOL. That laughter was soon modified when the owner of the car exited the book shop. Complete with pocket protector, a small slide ruler in it, and a copy of Einstein's "Collected Papers of Albert Einstein Vol 2". I had to find a toilet. Before I embarrassed myself, by urinating right where I stood. I still chuckle, anytime I am reminded of that!

Speaking of pocket protectors, I have never figured out where people buy them. Nowhere have I ever seen pocket protectors on sale, in any store, even though I see guys wearing them all the time (I suspect that they get them for free when they go to some sort of convention.) Not that I want one, or anything!

Kamog, NAH, you wouldn't want one!

They hand them out at every convention/conference I've ever been to. On average at a convention, you could pick-up eight(8) or nine(9). Two(2) or three(three) really nice ones. At a conference, one(1) maybe two(2). Cheap! The real dilemma is, just which one to use.
