Exercises for
Multiple Measurements of Quantum-mechanical Spin-1/2 Systems

The curricular material uses the OSP Spins program to show the effect of measurement on an ensemble of spin-1/2 particles.  In the virtual experiment, a beam of spin-1/2 particles leaves an oven incident on one or multiple ideal analyzers (ideal Stern-Gerlach apparatus) the result of which is detected as a click on a detector.

Before performing these virtual experiments it is important to first look over the tutorial and the tutorial exercises.

These examples depict the measurement of a beam of spin-1/2 particles (each green node sends in a different initial state through the analyzers) as they pass through an interferometer. One can choose the order of the measurement (for example: ZX or XZ) and also one can "watch" or "not watch" the particles go through the analyzers by toggling the purple button.

Note: For these exercises, the incident beam contains particles with randomly oriented spin orientations incident on the two ideal Stern-Gerlach analyzers that make up the interferometer.  Both first analyzers can be changed by clicking on them (blue).
