Is this the beginning of the Ansible and Jane?

If a photon traveling through a medium is required and the second atom has to receive that photon, there's no "instantaneous communication." If doing something to the first atom caused the second atom to respond in the same way in an immeasurable amount of time, then it's "instantaneous communication".

Unless I understood this wrong.

When it comes to Quantum mechanics, forget everything you know related to logic.

The photon was used only to entangle the atoms. Once they are entangled, there is no need to maintain a link between them. Whatever state the first atom changes to, the second atom will instantaneously change to that state. Communications with zero lag. Could use that for BF3.

I have only the smallest grasp of what is being talked about here, but it's really really cool!

Reminds me of Crichton and Timeline. Total fictional fabrication, but a really cool concept!

For a general, relatively (get it?) simple discussion of quantum mechanics, see chapter 7 of Brian Greene's "The Fabric of the Cosmos".

It will freeze your mind and make it numb.

Entangled pairs of atoms... can we call it DUOTRONICS?

quantum shit is whacked!

Mass Effect 2 communications technology, that's sooooo five hours ago.

Awesome news! My ISP needs to upgrade me to that 1 Exabyte per nanosecond connection already.

That is cool.

Brad, third paragraph, first sentence: "The scientists coaxed an atom into emitting a photon user a laser" I believe that user should be using.
