Summary: The Faculty of Physics at Warsaw hosts the Quantum Optics and Quantum Information group (Demkowicz-Dobrzański — world-leading in quantum metrology theory, quantum Fisher information, fundamental limits of quantum sensing) and experimental quantum optics groups (Wasilewski — quantum memory, photon-number-resolving detection). While theoretical strength dominates, the experimental groups are internationally competitive for quantum sensing protocols. The Polish quantum ecosystem is developing through the National Centre for Research and Development funding. Warsaw is an underrated destination for quantum metrology and quantum-enhanced sensing, particularly for theoretically-inclined experimentalists.

Notes: Poland's top university. Faculty of Physics: Demkowicz-Dobrzański group (quantum metrology theory, quantum Fisher information — internationally recognised), Wasilewski group (quantum memory, photon-number-resolving detectors, squeezed light). National Centre for Research and Development quantum funding. European Quantum Flagship associate member.

Warnings: The Demkowicz-Dobrzański group is world-class in quantum metrology theory and may be of interest to experimentalists who want strong theoretical support for quantum sensing projects.
