Can someone help with this subject:
What exactly is entanglement? How is it accomplished, and to what degree? And what is the explanation for it?

Tks
SirShanson
Should have posted this under Quantum Physics or somehwere else but anyway I'll try and answer the questions as best I can with what I know, somebody better endowed with Physics knowledge can come and expand later. Anyway here goes.

What exactly is entanglement?

Quantum entanglement is a strange quantum mechanical phenomenom, what it means in simple terms is that a particle can be "entangled" with another and as a result they will interact with each other regardless of their positions spatially with one another. This means that we can have one of the particles on either side of the world and by influencing one we can predict the state of the other particle I'd recommend reading Link for a better explanation.

It can be accomplished a number of ways I'll give as an example the case provided in the above link rather than a long incomplete list.

"A laser is shone at a crystal. In that case a single photon can split to become two photons. Each photon produced in this way will always have a polarization orthogonal to the other photon."

This is where I get off the boat completely I'm afraid, I'll leave that question down to somebody with deeper knowledge, hope what I could do gave at least a basic understanding.

I didn't realize I had posted under Creation/Evolution. Not much of a computer whiz, I'm afraid. I will follow up on the link you gave me. smile.gif

Quantum entanglement, for example photons is faster than light exchanging information at very far distance. But so scienciest think, that it can be explained, that photons initialy know how they must behave when they fly very far.
Here is enough easy explained about entanglement with two photons. http://quantumtantra.com/bell2.html
First crystal blue light converte to two entangled photons of red light and then those photons with arbitrary deegree polarization flying to polarized glasses in two oposit direction and depending how those two glasses polarization match then on this depending or photon behavtion will mutch or not mutch (when they going or not going through polarized glasses).

Electrons becaming entangled when they are near each over.

Brother, that Nick guy is just as wierd as he is intelligent. Maybe all that strange metaphysical nonsense has gotten the best of his mind. However, quantum entanglement sure is interesting, and he certainly understands it. I'm not sure I do, though. It sounds more like metaphysics than physics to me. But that seems the direction of science these days.

Quantum Entanglement explained. You impart a spin to two particles so together they equal "1" (not a real number). You can then measure one and you'll know the other one from that whether you measure the other instantly or at the other end of the universe. Just a conjuring trick of sorts.

Double slit experiment explained. Photons are waves. A wave is always divisible into smaller waves so you cannot have "one photon". The one photon/one wave splits into smaller waves so can go through all exits at the same time.

Your welcome and most people don't understand much more than the basics of it unless you head down routes at university which specifically cover it, your not alone!

Tks everyone.
I thought that one truth of quantum entanglement was that if you separated 2 entangled photons by any distance, and you interfered with one of them in ANY way, then that action would somehow be instantly mirrored or otherwise detected in the other. Hence, the use of entanglement for internet data protection.
