The essence of quantum physics and precision measurements lies in realizing the highly controllable interaction at the quantum level and the coupling between the quantum system and the external field. As a result, the evolution process of the quantum system can be deterministically controlled. Highly excited Rydberg atoms have exaggerated properties such as long lifetimes, large polarizabilities, giant dipole moments, and, most importantly, strong and long-range interactions. These unique features of Rydberg atoms enable highly controllable interactions and coupling with photons, making them an ideal platform for studying quantum physics and precision measurements. We employ these unique features to advance the quantum control of atoms and photons to a new level for studying quantum optics, many-body physics, quantum information, and precision metrology. Long-term goals include exploring novel quantum states of matter, creating macroscopic quantum entanglement, and testing fundamental physics.
