Development of ultra-cold strontium sample for optical tweezer arrays

Abstract

Neutral atoms are an advantageous candidate for quantum computation units due to their identical nature with high coherence. Many groups study strontium single atoms in optical tweezer traps to attempt high-fidelity quantum measurements with quantum computing potential. Our research aims to build a robust strontium tweezer apparatus to provide an ultra-cold Sr sample with μK level temperature. The prepared sample is further trapped in the optical tweezer arrays, where a few thousand atoms are trapped across tens of tweezer sites. Ultimately, we plan to only trap a single atom in each tweezer site and conduct high-fidelity quantum gate operations. In this thesis, I will give a complete guide to our strontium apparatus, introduce the necessary setups to achieve optical tweezer traps, and provide the experimental findings.
