Two-stage ablation loading for quantum information processing (QIP) systems

A quantum information processing (QIP) system comprising:

• an ablation laser beam source configured to generate an ablation laser pulse;
• an external light source configured to generate a first laser beam;
• an ion trapping structure including:
• an enclosure with an orifice,
• a source material that is arranged in the enclosure and receives the ablation laser pulse to provide a plume of atoms;
• an opaque substrate that is arranged in the enclosure and receives both the first laser beam and at least a portion of the plume of atoms, causing desorption of at least one atom through the orifice of the enclosure;
• and
• an ion trap with a gap through which the at least one atom travels from the orifice;
• and
• a laser beam source configured to generate a second laser beam towards the at least one atom creating a trapped ion.
