  Recent progress in the development and applications of microstructured
optical fibres for quantum technologies is summarised. The optical nonlinearity
of solid-core and gas-filled hollow-core fibres provides a valuable medium for
the generation of quantum resource states, as well as for quantum frequency
conversion between the operating wavelengths of existing quantum photonic
material architectures. The low loss, low latency and low dispersion of
hollow-core fibres make these fibres particularly attractive for both short-
and long-distance links in quantum networks. Hollow-core fibres also promise to
replace free-space optical components in a wide range of atomic experiments.
