Ion loading system and ion loading method

Abstract

The invention discloses an ion loading system and an ion loading method. The ion loading system comprises a laser generator, an electric control scanner, a target material and an ion trap. The laser generator is suitable for emitting laser, the electric control scanner can enable a laser light path to deflect, the electric control scanner is suitable for changing the laser emitting direction, the target material ejects atoms at the ablation position under ablation of the ablation laser, and the ion trap is arranged adjacent to the target material and is suitable for collecting the atoms ejected by the target material. The electronic control scanner is arranged to change the position where the ablation laser irradiates the target material, the situation that the number of sprayed atoms is reduced due to the fact that the ablation laser ablates the same position of the target material for a long time and the target material is damaged and sunken is avoided, and therefore the service life of the target material can be prolonged, the number of generated ions is large, the speed is stable, and the efficiency is high. The working efficiency of the ion loading system is high.

Description

technical field [0001] The invention relates to the technical field of ion trap quantum computing, in particular to an ion loading system and an ion loading method. Background technique [0002] In the ion trap quantum computing system, ions are needed as carriers for bit storage and operation, so loading ions needs to be prepared in advance. The steps of loading ions are generally three steps: evaporation of atoms, ionization, cooling and trapping. The method of evaporating atoms is generally to ablate the target with high-energy pulsed light, and eject a large number of atoms at the ablation position. [0003] In the process of evaporating atoms with pulsed light, during the long-term ablation of the target material, the position of the target material irradiated by the pulsed light will be recessed, which will lead to a large reduction of ejected atoms in further ablation, which does not It is beneficial to the long-term work of ion trap quantum computers. SUMMARY OF T...
