  We establish the equivalence between the loss of coherence due to mixing in a
quantum system and the loss of information after performing a projective
measurement. Subsequently, it is demonstrated that the quantum discord, a
measure of correlation for the bipartite system $\rho_{Alice\leftarrow Bob}$,
is identical to the minimum difference (over all projectors {|i><i|}) between
local coherence (LQICC monotone) on Bob side and coherence of the reduced
density matrix $\rho^B$.
