Quantum Optical Devices Laboratory

The QOD Lab led by Michał Parniak 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 ultranarrowband and ultrafast regimes. Applications of such atomic systems range from communication, where they can operate as transmitter or receiver, to quantum sensing.

Information for prospective students:

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 a diverse background, 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”.

Possible BSc (licencjat) or MSc (magister) projects:

  • Quantum-inspired superresolution imaging via arrayed-homodyne detection (physics)
  • Generation of Rydberg atoms: towards strong photon-photon interaction in 3D (experimental physics, theoretical physics)
  • Super-resolution spectroscopy of ultrafast broadband light (experimental physics)
  • Digitial signal processing solutions for quantum experiments (experimental physics, computer science, information technologies

The theses can be prepared and defended as part of the studies at the Faculty of Physics (FUW), University of Warsaw. Other options can be discussed as well, such as Faculty of Mathematics, Informatics, and Mechanics (MIM), University of Warsaw, or Warsaw University of Technology (PW).

If you are interested do not hesitate to contact Michał Parniak at m.parniak@cent.uw.edu.pl to schedule a visit in the lab, with an opportunity to talk with other students.

Contact us also if you are motivated to work in the lab but do not have previous research experience!
