Homework Statement I am trying to find the possible measurement results if a measurement of a given observable ##Q=I-\left|u\right\rangle\left\langle u\right|## is made on a system described by the density operator ##\rho={1 \over 4}\left|u\right\rangle\left\langle u\right|+{3 \over...

Chopin, thank you for your reply. In answer to your question, no there is nothing specifically that I was looking for to happen. My confusion lay in the fact that most of the sources I read use ambiguous language like 'resolve' the degeneracy, or 'remove' the degeneracy, and I was confused as to...

When finding a complete set of commuting observables, the goal, as I understand it, is to specify enough observables in the set such that, when given an eigenvalue of a state from each observable's matrix, these eigenvalues uniquely identify a corresponding eigenvector. It seems that every...
