Coherent control of single photon sources is a key requirement for the advancement of photonic quantum technologies. Among them, nanowire-based quantum dot sources are popular due to their potential for on-chip hybrid integration. Here, we demonstrate on-demand single-photon generation g(2) (0) (X*) = 0.078 from resonantly excited InAsP/InP nanowire quantum dots and observe Rabi oscillations in the dot emission, indicating the successful coherent manipulation of the excitonic states in the nanowire. This work addresses the long-standing challenge of resonantly exciting nanowire-quantum dots. It paves the way for hybrid quantum photonic integration, enabling spin–photon entanglement and matter memories on-chip.
