A system of just 30 cold neutral atoms among which the interactions can be coherently controlled would surpass the calculation power of the current fastest classical supercomputer. Its utmost computing speed will unprecedentedly accelerate methodological advances in all disciplines and inevitably introduce to technological revolution. To exploit the power of quantum computing, deterministic preparation of single atoms in a fiducial state is a crucial step. For that, a novel versatile focused-beam trap (FBT) is being implemented in our lab. When fully manipulated, the system can be scaled up to trapping in 3D optical lattices, one of the most promising candidates that play an important role in neutral-atom-based quantum logic devices and quantum memory. The picture shows our simulation of what might be realized in a few months.
