We investigate cooperative behavior of three and four quantum emitters coupled to a common nanophotonic structure. We theoretically demonstrate that strong dipole-dipole interaction is attainable for emitter distances on the order of the operating wavelength in a couple of judiciously designed systems, including epsilon-near-zero parallel plate waveguide, SOI microring resonator, and silicon microshell/silica core structure. We also show that a high-purity W state can be generated with high efficiency in such systems, making them promising candidates for the generation of long-range quantum entanglement between multiple qubits.
