Which makes the answer to the first question "only if Alice tells him her outcomes", and that makes the answer to the second "no."
Welcome to PhysicsForums, realbart!Let's do a thought experiment.
...
q: Does Bob learn the direction Alice is measuring at?
q: Does this violate the no-cummunication theorem?
You're absolutely right, Heinera. I expected to see the graph as function of the angle between the measurement and the Z-axis.The graph you have enclosed is a plot of the correlations between Alice's and Bob's measurement results. Bob (without knowing Alice's results) can not make this plot by himself.
Bob's measurements will be completely random to him, no matter what axis he chooses. They will be "up" or "down" with 50/50 % probability.You're absolutely right, Heinera. I expected to see the graph as function of the angle between the measurement and the Z-axis.
So let's say Alice will measure every particle spin along the Z-axis.
What will Bobs measurements be along the horizontal plane? (perpendicular to the Z-axis)
