Quantum Optical Devices Lab (QODL)

The Quantum Optical Devices Laboratory studies the fundamentals and applications of optical devices operating in the quantum regime. Our focus is on imaging systems, where we use quantum information theory to improve classical imaging systems and work to develop new imaging methods that exploit the full quantum information present in the optical field. We are also studying quantum nonlinear processes in atomic media to implement quantum image processing at the level of single photons. To this end, we seek to exploit giant Rydberg atoms that can mediate interactions between photons. Finally, we also use atomic media to explore imaging in the time and frequency domain, both in the ultranarrowaand and ultrafast regimes. Applications of such atomic systems range from communication, where they can operate as transmitter or receiver, to quantum sensing.

Dr Michał Parniak-Niedojadło is a junior group leader in the Centre for Quantum Optical Technologies QOT. His research interests cover a range of topics in quantum optics, such as single photon detection, optical quantum information processing and communication, atomic ensembles, nonlinear optics and quantum optomechanics. Within QOT he develops experimental implementations of quantum protocols designed by the theory groups, and maintains close experimental collaboration with prof. Wojciech Wasilewski (QOT) and prof. Eugene Polzik (Niels Bohr Institute, University of Copenhagen).

We are always looking for prospective candidates to perform exciting work in experimental Quantum Information Science in our lab. Our group collaborates with the team of Quantum Memories Lab on various projects involving atomic physics. We also work with the Quantum Technologies Lab (Konrad Banaszek, Marcin Jarzyna), Quantum Metrology group from FUW (Faculty of Physics UW) of Rafał Demkowicz-Dobrzański, as well as the group of Krzysztof Jachymski from FUW working on atomic aspects of our experiments. Our projects combine experimental and theoretical aspects. Our team involves members with diverse backgrounds, ranging from theoretical quantum information to practical mechanical and electronic engineering.

Prior experience in experimental or theoretical quantum optics is not required at BSc level. Yet we are looking for candidates with strong dedication. We offer help and guidance in the now broad field of quantum information, as well as guidance in applying for additional funding such as scholarships or “Diamentowy Grant”.
