PhoQuS fostered research topics

Two research areas of particularly high potential and recognizable accomplishments at the Faculty of Physics UW are AttoScience and Quantum Optics. In addition a new researched direction - Biomedical Optics - will be established within this project.

Groups involved in the project

Equipment upgrades

PhoQuS project investments will complement major research infrastructure and equipment upgrades that have been carried out with vast investments from European Structural Funds. The proposed purchases used extensively in application-driven research:
