The realization of large-scale fully controllable quantum systems is an exciting frontier in modern physical science. We use atom-by-atom assembly to implement a platform for the deterministic preparation regular one-dimensional arrays individually controlled cold atoms. In our approach, measurement and feedback procedure eliminates entropy associated with probabilistic trap occupation results defect-free more than 50 atoms less 400 milliseconds. technique based on fast, real-time control 100 optical tweezers, which we arrange desired geometric patterns maintain these configurations by replacing lost surplus from reservoir. This bottom-up approach may enable engineering scalable many-body information processing, simulations, precision measurements.
