Quantum Technologies with Atomic Systems

Hot atomic vapors have played a central role in the development of modern atomic physics and continue to provide a remarkably versatile platform for exploring light–matter interaction. While research over the past decades has strongly focused on cold and ultracold atomic systems, thermal vapors remain highly attractive due to their experimental simplicity, robustness, and scalability. These properties make them particularly promising for the realization of compact and reliable quantum technologies.

Recent advances in spectroscopy, coherent control, and nonlinear optics in warm alkali vapors have opened new perspectives for both fundamental research and applications. Phenomena such as coherent population trapping, electromagnetically induced transparency, four-wave mixing, spin squeezing, and Rydberg-mediated interactions can now be harnessed in miniaturized vapor-cell platforms. As a result, hot atomic systems are emerging as key components in quantum-enhanced sensing, precision metrology, compact frequency references, magnetic and electric field sensing, and imaging techniques.

This workshop aims to bring together leading European researchers working on the fundamental physics and technological applications of hot atomic vapors. By fostering exchange between experts in spectroscopy, quantum optics, nonlinear dynamics, and device development, the meeting will highlight recent breakthroughs, identify open challenges, and stimulate new collaborations. Particular emphasis will be placed on bridging fundamental understanding and practical implementation, with the goal of accelerating the transition of vapor-based quantum systems from laboratory research to real-world applications.

The workshop seeks to strengthen existing collaborations and create new connections within the European research community.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
