In recent years, Rydberg atoms have emerged as a promising platform for quantum sensing, enabling the detection of electromagnetic fields across a wide frequency range from MHz to THz. Atomic media offer broad tunability, high quality factors, and intrinsic calibration based on the Autler–Townes effect. However, most existing protocols still do not surpass conventional electronics in terms of sensitivity. Nevertheless, atom-based measurements hold the potential to approach the fundamental limits of electromagnetic field detection. The talk will present our efforts to develop novel Rydberg sensing protocols in both hot and cold atomic ensembles, including interaction-assisted measurements and multi-wave mixing techniques.
Seminar will take place on 26 March 13:00 val. at NFTMC D401 auditorium.
About the speaker
Dr Michał Parniak is a group leader at the Centre for Quantum Optical Technologies (Centre of New Technologies) and an associate professor at the Faculty of Physics, University of Warsaw. His research experience spans quantum optics, optomechanics, Rydberg atoms, and atomic physics. Before joining QOT, he worked as a postdoctoral researcher at the Niels Bohr Institute, University of Copenhagen. His group currently aims to combine fundamental quantum physics with applications in quantum sensing, metrology, and information processing, with a particular focus on bringing quantum technologies to the space industry.
All interested in quantum materials, semiconductor physics, and next-generation quantum platforms are welcome to attend.
