spectral theorem and probabilities Flashcards
1
Q
Key axiom of quantum theory
A
2
Q
Eigen state
A
|ψ> etc
3
Q
If |Ψ> is not an eigenstate of Ο^^ and we measure Ο^^ in that state, then we measure again in say |Φ> state;
How do we understand this?
A
4
Q
Why are all real observable quantities represented as self adjoint operators
A
Due to states being eigenstates of observables with eigenvalues as below
Requires observables to be Hermitian
5
Q
Eigenvalue has multiplicity
A
For each λ we have several eigenstates
