- Homework Statement
- Measure Sz from the following expression see pic.
- Relevant Equations
Operators Sy and Sz represent standard spin vectors and w is a positive constant.
So this expression is apparently in Sz basis? How can you see that?
How would it look in Sy basis for example?
The solution is following. They are putting Sz as a basis, bur how do you know that Sz is the basis here?
