Neutral Atom Platforms

Cold Atoms

Cold atoms provide a highly controllable platform for studying quantum systems, precision measurement, and emerging quantum technologies. By laser cooling and trapping atoms in a magneto-optical trap, researchers can create clean atomic ensembles whose motion and internal states can be precisely controlled. These systems are useful for exploring quantum sensing, atom-light interactions, and future quantum technologies. In this research area, POSM is developing the experimental infrastructure for rubidium cold-atom research, including laser cooling, optical control, atom trapping, and sensing-oriented atomic physics experiments.

Rydberg Sensing

Rydberg atoms are highly excited atoms whose strong response to electric fields makes them useful for precision sensing and studies of light-matter interaction. Because their properties are determined by atomic structure, Rydberg systems offer a unique platform for measuring radio-frequency and microwave fields using optical techniques. These capabilities have potential applications in field sensing, spectroscopy, and quantum technology. In this research area, POSM is exploring Rydberg-based sensing concepts built on cold atoms, laser control, and optical readout.
