First of all, thanks alot for the replies so far, much appreciated. I have been reading more about quantum mechanics whenever I can find the time, and I have yet another question regarding uncertainty.
I'm new to all of this, so please correct me if I make any mistakes along the way. The question I am asking here regards uncertainty and quantum entanglement.
Imagine we have a source of entangled electrons, one going to the left towards observer A (Adam), and the other to the right, towards observer B (Brad). First off, we will measure the electron spin on axis Z, allowing two possibilities, Ia (z+, z-) and IIa (z-, z+). If Adam measures the electron at z+, then we know Brad's electron must be z-, due to them being entangled (right?).
Now, if Brad then measures his electron on the x axis, we know there will be one of two possibilities, Ib (x+, x-), or IIb (x-, x+). So say Brad measures his electron to be x-, we now know that Adams electron must be x+. According to uncertainty, we can not know for certain the spin of an electron on both the x and z axis, but if the two observers are to compare notes, we will know that Brads electron is z- and x-, and Adams electron is z+ and x+.
First of all, have I got this thought experiment right? Secondly, does this not violate the uncertainty principle?
