B Does weak measurement cause mixed state?

    Does a 'weak measurement' on the spin of an electron in a pure state put the electron in a mixed state of the previous state and the state of the measurement axis of the measurement?

    I think it is in a superposition of those states, not a mix. After a suitable weak measurement, that is.
