SUMMARY
The discussion focuses on calculating the probability of +z atoms passing through a series of Stern-Gerlach selectors, specifically a +x selector followed by a -z selector. The initial state of the atoms is represented as |\uparrow_z>, and after passing through the +x selector, 50% of the atoms are polarized in the +x direction. Subsequently, when these +x polarized atoms encounter the -z selector, 50% of them will pass through, resulting in a total probability of 25% for the atoms to successfully pass through both selectors.
