We show that it is possible to realize significant nonlinear optical
interactions at the few photon level in graphene nanostructures. Our approach
takes advantage of the electric field enhancement associated with the strong
confinement of graphene plasmons and the large intrinsic nonlinearity of
graphene. Such a system could provide a powerful platform for quantum nonlinear
optical control of light. As an example, we consider an integrated optical
device that exploits this large nonlinearity to realize a single photon switch.
