PI bio

Łukasz Rudnicki is a physicist working in the field of quantum information, with emphasis on quantum optics and open system dynamics. Łukasz received his PhD in 2012 at the University of Warsaw, while working in Center for Theoretical Physics PAS. Then he was a postdoc in Freiburg and Cologne, and recently, a senior scientist in Max Planck Institute for the Science of Light in Erlangen. Currently, Łukasz is a group leader at International Centre for Theory of Quantum Technologies (ICTQT) and deputy director of National Quantum Information Centre, both located in Gdańsk. He is a coordinator of QuantERA ApresSF project and a full partner in the Stormytune EU project within FET Open. Łukasz also represents Poland in Quantum Community Network, an advisory body of the Quantum Flagship.

Short description of research profile

Aims:

To explore intersections of quantum optics, quantum thermodynamics and open system dynamics.

Description:

The group’s research interests lay within standard quantum optics, currently, looked at from the perspective of open quantum systems and thermodynamics. We also extensively collaborate with experimental groups concerned with quantum technologies, with emphasis recently put on metrology.

Open Quantum Systems and Quantum Optics

Among various topics of our interest there are: bosonic systems at a mesoscopic scale, open quantum evolution of Gaussian systems, limitations concerning quantum batteries, non-Markovian dynamics, interplays between work and coherence, as well as potential thermodynamic advantages of indefinite causal order.

Quantum Metrology

We coordinate the QuantERA project “Application-ready superresolution in space and frequency” (ApresSF), and take part in Horizon 2020, FET Open project “Spectral-Temporal Metrology with Tailored Quantum Measurements” (Stormytune). Both projects are devoted to superresolution in quantum metrology.

Projects/grants:

Application-ready superresolution in space and frequency (ApresSF)

Spectral-Temporal Metrology with Tailored Quantum Measurements (Stormytune)
