## Abstract

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 $\\rho^B$.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
