Coherent control of motion of atoms in optical tweezers

I will first give a brief overview of ongoing development of neutral-atom quantum processors in Japan Moonshot program for fault-tolerant quantum computers. In particular, I will emphasize the rather unique collaboration between academic and industrial partners in the USA (Infleqtion) and in Japan (National Institutes for Natural Sciences, Kyoto University, RIKEN Quantum Computing Center, Hitachi and Yaqumo).

Then, I will highlight our our ongoing research directions pushing the control of the motion of individually trapped atoms, with impact in quantum simulation, computation and fundamental science. This will cover recently published works on spin-motion entanglement due to the van der Walls interaction (PRL 113, 093405 (2024)), as well as the demonstration of squeezing of motion of atoms in optical tweezers (arxiv:2505.10092). I will conclude with a vision of how coherent control of the motion of atoms could be used to perform quantum gates with Rydberg atoms in a yet unexplored regime.
