【题   目】 Manipulation of photonic and atomic states via nonlinear interactions 

【摘  要】 Nonlinearity plays a crucial role in the generation of nontrivial quantum states, with demands spanning a wide spectrum from fundamental physics research to practical technological advancements. In this talk, I aim to introduce our recent work on the manipulation of photonic and atomic states through the strategic utilization, control, or design of nonlinear interactions. Two remarkable accomplishments will be highlighted: first, the deterministic generation of photon pairs within confined one-dimensional systems, and second, the development of an entanglement filter using Rydberg atoms in free space. Beyond our exploration of photonic states, I will also present our latest work on atomic magnetometers whose performance is highly dependent on the atomic-spin states. In closing, I shall provide forward-looking perspectives on the trajectory of our research.
