Entanglement in Quanta Mechanics

Entanglement is what happens when two parts of a system were at one time inter in. And then, even if you remove the inneraction, they have a memory having done that. So almost anything that constitutes an interaction that needn't be can create entanglement. In about a nana second or something, the whole universe knows and oi down load the picture when they want. That's how long it takes for the picture to be all over the world.
