Abstract
General quantum correlation measures such as quantum discord, one-norm geometric quantum discord exhibit freezing, sudden change, and double sudden change behavior in their decay rates under different noisy channels. Therefore, one may attempt to investigate how the freezing behavior and other dynamical features are affected under application of local quantum operations. In this work, we demonstrate the effect of local filtering on the dynamical evolution of quantum correlations. We have found that using local filtering, one may remove freezing depending upon the filtering parameter.
