Abstract: Recently, cold neutral atoms trapped in optical tweezers have attracted much attention as a platform for quantum computing. In our group, we are developing an "ultrafast quantum simulator and computer," in which single 87Rb atoms in an optical tweezers array are excited to a Rydberg state with picosecond pulsed lasers. In such systems, in particular for large-scale quantum simulations and computations, it is necessary to develop a quantum-state readout technique without losing the atoms during the measurement process. We have performed this non-destructive state-selective measurement with fluorescence imaging of the atoms. This experiment was performed with an integrated laser system manufactured by Muquans, which is compact and convenient for quantum manipulation of the atom by packaging optics and control systems. In this presentation, I will introduce our group research briefly first, and discuss our latest research results and the plan for the next-generation system.
