There's no quantization there.
Uh in this in the spin case, on the one hand, instead of an infinite number of possible outcomes, you always have one of two possible outcomes when you do the experiment.
So it simplifies in that way.
But in the other direction, instead of only having one or two possible experiments you can do, you have an infinitude of possible experiments you can do because you orient your skr Stern Gerlock magnet and you can twist that magnet however you want.
Right.
You can have it this way or this way or forty five or thirty or sixty.
And so you now have.
An entirely new palette of practically doable experiments from which you can get this data.
And that's that second part is what's gonna lead us to Bell's theorem.
What just as in the original EPR case, the experimenters can by their own whatever way they want decide whether to measure position or momentum.
Here are two experimenters, Alice and Bob, can in whatever way they like.
orient, determine the orientation of this Stern Gerlock magnet.
So all of those orientations are available to them.
They can use any choice procedure they want to pick in a on a particular run of this experiment how the magnet should be set.
So we wanna when we indicate a spin experiment, one thing we have to do is indicate the direction of the magnet.
We have to give a direct this doesn't come in the original EPR case, because that wasn't any they weren't orienting anything.
And so we speak of X spin or Y spin or Z spin or 45 degrees between X and Y spin, where all of those just indicate a direction in space.
And that's going to be the direction that points from, say, the south to the north pole of my magnet.
And it can be anything.
And when no matter how I orient the magnet, I'll always either get one of these two outcomes, which are typically called spin up or spin down outcomes.
