I have a sample IBM experience circuit which generates $$\frac{1}{2}(|00\rangle - |01\rangle - |10\rangle + |11\rangle)$$ When we measure the state will be either $|00\rangle$/$|01\rangle$/$|10\rangle$/$|11\rangle$.
I know that state phase disappears after measurement. I am testing a complex circuit which involves phase angles and I want to ask my questionusing a simple state as mentioned above.
Is there anyway to know if the circuit has produced my desired state. I want to view the full state.
