Quantum Optical Devices Laboratory (QOD Lab)
Lab Leader: Dr Michał Parniak
The QOD Lab led by Michał Parniak (assistant professor at Optics Division, Institute of Experimental Physics, Faculty of Physics) 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.
