Quantum levitodynamics is the field of research that studies the quantum motion of mesoscopic objects levitated, e.g., in optical tweezers. In this field, the so-called spraying method is conventionally used to load the particle to an optical trap stochastically, limiting the efficiency and selectivity of the trapping. To address this, we are developing an efficient method for selectively loading nanoparticles into an optical tweezer. This approach involves first selectively imaging the particles on a surface and then loading them into an optical tweezer, enabling the trapping only the particle of interest. The loading process is achieved through vibration-induced acceleration, which allows particles to be efficiently shoot into the tweezer. We present our recent progress toward achieving this goal.
