They are identical in every way, except one is red and the other is blue. I randomly grab one in each hand and show my hands closed. Now the states of the ball are entangled: as soon as you see the color of one ball, that &quot;determines&quot; the color of the other. (Not claiming that this is a perfect analogy, but I don&#x27;t see where it diverges from how entangled quantum waves would behave.) &gt; Among the fundamental differences is the fact that classical information can be copied but quantum states cannot be cloned.
