Abstract

Remote coupling between quantum emitters is of great importance for constructing quantum networks. Conventionally, this can be achieved via photon exchange by incorporating the quantum emitters in a waveguide or a large cavity.However, such photonic structures suffer fromlowquality-factors or large mode volumes, limiting the efficiency of light-matter interaction. Here, we demonstrate remote coupling between two site-controlled semiconductor quantum dot emitters mediated by an optical Fano resonance induced by coupling cavity modes via a continuum waveguide state.Unlike ordinary coupled modes, the Fano mode offers both a spatially extended field and a high local density of optical states at the emitters, enhancing light-matter interaction. This coupling scheme allows the demonstration of mutual excitation between two quantum dots separated in space by
