A loading assembly configured for providing atomic objects to an atomic object confinement apparatus is provided. The loading assembly comprises one or more ovens. Each oven (a) comprises a respective oven nozzle and (b) is configured to generate a respective atomic flux of a respective atomic species via the respective oven nozzle. The loading assembly comprises a mirror array and a magnet array configured to, when optical beams are provided to the mirror and magnet assembly, generate a two-dimensional magneto-optical trap (2D MOT). The 2D MOT is configured to generate a substantially collimated atomic beam from the respective atomic fluxes generated by the one or more ovens. The loading assembly further comprises a differential pumping tube defining a beam path. The differential pumping tube is configured to provide the substantially collimated atomic beam via the beam path. The respective oven nozzle of each of the one or more ovens is misaligned with the beam path and the 2D MOT is configured to provide the substantially collimated atomic beam in alignment with the beam path.
