- questions about Pauli matrices -
why do they need to be Hermitian, what are they trying to measure and why do they need to
satisfy that those matrices squared equals the identity matrices.
Hi :)
I have several questions about the Pauli matrices,
I have seen them when the lecturer showed us Stern-Gerlach experiment
, and we did some really weird assumptions on what we think they should be.
1- why did we assume that all of those matrices should satisfy
σ2 = I (the identity matrices)
2- why do they have to be Hermitian?
3- what they are trying to measure? (when we insert <-| for example, we get -<-|, why is that? )
thanks for helping !
