Engineering two-qubit mixed states with weak measurements

It is known that protocols based on weak measurements can be used to steer quantum systems into predesignated pure states.Here we show that weak-measurement-based steering protocols can be harnessed for on-demand engineering of mixed states.In particular, through a continuous variation of the protocol parameters, one can guide a classical target state to a discorded one, and further on, toward an entangled target state.
