I'm just getting the basics of quantum mechanics and I had a question regarding a modification of the stern-gerlach experiment that I think might help me understand the superimposed eigen-states better. Could someone please clarify what one would expect in the following situation? Suppose we take a *single particle* and pass it sequentially through the following set of filters SGz, SGx, SGz, SGx, SGz, SGx, .... so on what will the measured values of the particle's spin be? Say the result of the first two filters is +, - then will the following filters also record +,-,+,- so on or will the sequence be completely random? Will the result predicted by QM depend on what sort of interpretation one subscribes to, for example copenhagen vs statistical or deterministic vs non-deterministc?
