Quantum Seminar: Talk on Quantum Electromagnetic Sensing

On March 26 (Thursday) at 13:00, the next event in the Quantum Seminar series will take place in room D401. The talk will be given by Dr Michał Parniak (University of Warsaw). 

Title: Frontier of electromagnetic measurements via quantum sensing with Rydberg atoms

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.

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.
