摘要：

We employ the entropic uncertainty relations and the quantum Fisher information to explore the formation of quark tt<overline> pairs at the Large Hadron Collider through the combination of qq<overline> pair and gg pair initiated processes. A comprehensive analysis has been undertaken on the procedure of quark and gluon channel mixing in the production of top quark pairs tt<overline>, encompassing the tightness of the entropic uncertainty inequalities and the maximum quantum Fisher information of the system.
