One of the curious properties of quantum physics is that a particle state or property, such as its spin or position, cannot be known until it is measured. The active measuring changes the state of the second photon to match the state of the third. As soon as the second photon changes, the first photon on the receiving end of the quantum channel snaps into a matching state. Step number five complete the teleportation
But anyway, it's a really interesting article and there's so many implications of that, of actual teleportation. That's a whole different discussion, I think, in terms of consciousness, is it you only who reappears at the other end? There's a whole different kind of level of interesting question that can be asked. But just in terms of this article, this is good to see this experiment, but very, very far away from moving anything physical from one place to another
