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.

Ion trap loading assembly

The disclosure provides an atomic object trap apparatus and a method of operating such. The atomic object trap apparatus comprises two or more radio frequency (RF) electrodes formed concentrically in a substantially elliptical shape; and three or more trapping and/or transport (TT) electrode sequences formed concentrically in a substantially elliptical shape. The two or more RF electrodes and the three or more TT electrode sequences define a substantially elliptically-shaped atomic object trap. At least one TT electrode sequence of the three or more TT electrode sequences is disposed concentrically between the two or more RF electrodes. Each RF electrode and TT electrode sequence is elliptically shaped such that each comprises two substantially parallel longitudinal regions and two arc-spanning beltway regions, the four regions forming a substantially elliptical shape. The method is directed to operating a quantum computing system comprising an example atomic object trap apparatus.
