On Demand Single Photon Generation and Coherent Control of Excitons from Resonantly Driven Nanowire Quantum Dots

Coherent control of single-photon sources is crucial for the advancement of many photonic quantum technologies. In this work, we demonstrate on-demand single-photon generation and coherent manipulation of excitons in InAsP/InP nanowire quantum dots (NW QDs) (Fig. 1(a)) under resonant excitation. Nanowire quantum dots are promising candidates for hybrid photonic integration due to their deterministic growth[1], high extraction efficiency[2], and precise spatial positioning capabilities[3].
