Greetings - I have a question about observables and Quantum Mechanics.
Let's say I want to measure the spin state of a particle.
If I measure σZ (sigma Z), I will get either +1 or -1. That will then prepare the spin state accordingly.
If I measure σX (sigma X), I will get either +1 or -1. That will then prepare the spin state accordingly.
If I measure σY (sigma Y), I will get either +1 or -1. That will then prepare the spin state accordingly.
What if I measure all three axes simultaneously? Won't that then give me three different resultant spin states, when there can only be one?
