Parabolic cassegrain-type reflector for ablation loading

A quantum information processing system, comprising:

• a vacuum chamber;
• an ion trap including a loading aperture;
• one or more laser sources configured to control a plurality of ions in the ion trap;
• an optical controller configured to operate the one or more laser sources to perform quantum processing;
• a reflector having opposing first and second surfaces with a hole extending therethrough, the hole being aligned to the loading aperture of the ion trap;
• an optical source configured to generate a plurality of laser beams towards the first surface of the reflector;
• and
• an atomic source positioned between the optical source and the reflector,
• wherein the first surface of the reflector is structurally configured to reflect and focus the plurality of laser beams onto a surface of the atomic source to generate an atomic plume in response thereto that is directed through the hole extending through the reflector and into the ion trap via the loading aperture.
