Here, Graphene clad plasmonics waveguide is introduced as a two surface plasmonic polariton modes interference (GTSPPMI) coupler to obtain optically manipulated quantum interference. The manipulation of Handel Ou Handel (HOM) quantum interference is demonstrated theoretically in nano-scale two modes coupler through refractive index modulation in Graphene clad with incidence of an ultra fast optical pulse energy. The quantum entanglement of fidelity ~ 97.5% is obtained by incidence of optical pulse of energy 5.12 pJ and width 3.8 ps in Graphene cladding. Our results promise to obtain fast and compact optical reconfiguring of quantum plasmonics circuit in comparison to electrooptic and themooptic coupler.
