The Quantum Photonics (QP) Section investigates optical quantum phenomena at the single-/few-photon level, such as coherence, entanglement and squeezing, to develop novel methods of measurement, sensing, and imaging.
These advancements may result in significant improvement in the precision with which physical parameters of a wide range of systems can be estimated. The section also addresses the need for metrology and standards for quantum communication systems and the general traceability of photonic quantum metrology and sensing. These applications require the development of techniques that are robust to noise and imperfections, i.e., to fit to real-world scenarios.
The research is focused on:
- Traceability of measurement at the single photon level
- Development of new physical and documentary standards
- Metrology for quantum communications (in fiber and space)
- Quantum enhanced imaging
- Quantum sensors (e.g. magnetism, pressure and temperature based on color centers, sensors based on squeezed and entangled light)
