The use of optical nanofibres, that is silica optical fibres with a subwavelength
diameter, in quantum systems is already well-documented with a large number
of theoretical and experimental studies reported during the last two decades.
Optical nanofibres can provide very high intensity electric fields with a very
steep field gradient at their surface. Such an electric field can be used to study
spin-selection rules in single-frequency, two-photon excitation via non-paraxial
light or electric quadrupole excitations in atomic systems. Here, I will discuss
our recent work on integration of Rydberg atoms with optical nanofibres with
the aim of designing a 1D chain of Rydberg with interactions mediated via the
nanofibre. I will also show how machine learning can optimize the trap
occupancy in fibre-based dipole traps and present some nanofibre based
cavity designs suitable for cavity QED
