Nanowire quantum dots grown using vapour-liquid-sold epitaxy have demonstrated quantum optical
properties approaching that of state-of-the-art self-assembled quantum dots. Advantages of the nanowire
system is a growth mode that allows for (i) position-control without loss in optical quality, (ii) control of the
number of emitters per device and (iii) near-unity yield of high efficiency devices. In this talk, I will cover
the growth technique used to produce position-controlled nanowire-based sources of non-classical light and
summarize their performance with regard to single photon purity, two-photon interference visibility and
fidelity to a maximally entangled Bell state. I will also discuss future directions, including multiplexed single
photon sources based on multi-dot nanowires and monolithic integration based on evanescent coupling to
SiN waveguides
