So far, the super one-way deficit by 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.
