“How would you represent the probability of the following output using bra-ket notation?”
After using the SPINS Stern-Gerlach simulator for experimentation, students benefit from revisiting how the experimental setup is represented in bra-ket notation. This small whiteboard question is useful for exercising students' ability to move between different representations. Here, students must translate the physical experiment
Additionally, this SWBQ finds natural inclusion in the Stern-Gerlach sequence and can be incorporated as an extension of many of the listed activities.
