Help me, Science! You’re my only hope!

Okay, so…

Every now and again, we see news articles about scientists having developed technology that could lead to teleportation, or (more likely) instant communication. It involves paired particles that, regardless of the distance between them, react in exactly the same way if one of the pair is subject to an outside force.

Can someone give me a more detailed description and explanation of this process, and the theory behind it? More importantly, it needs to be an explanation that’s at least mostly comprehensible by a layman who’s barely qualified to take a high school physics class. 😳
