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

 

Three Analyzer Follow Up Questions

~~1. What is unique about the statistical mixture as compared to the eigenstate and superposition states?  Hint: Can you write down the state of each spin-1/2 particle that comes out of the oven for a statistical mixture? How about for an eigenstate?  A superposition of eigenstates? 

~~1. What would happen to the % of counts if instead of two analyzers there were three?  Specifically, if the analyzers were arranged in a similar fashion with the "up" of the second analyzer sent to a third SG analyzer (either XZX or ZXZ)?
