Abstract
So far, the super one-way deficit in weak measurement has been calculated explicitly only for a limited set of two-qubit quantum states and expressions for more general states are not known. In this paper, we extend the previous studies to 2 ⊗ d quantum systems and derive an analytical expression for a two-parameter class of states for d ≥ 3. We compare quantum discord and super one-way deficit for qubit-qutrit systems. We find that super one-way deficit is smaller than the quantum discord. On the other hand, by tuning the weak measurement continuously to the projective measurement, both super one-way deficit and quantum discord converge to the same value.
