Highlights
Great success for the first symposium on Diamond Photonics at EPFL
The organisers, Niels Quack and Christophe Galland, thank all participants who made the Latsis symposium on Diamond Photonics such a thrilling event on May 19-22, 2019!
Internal vibrations mediate quantum correlations
Our group has developed a new technique to probe elementary quantum excitations of atomic vibrations inside a crystal under ambient conditions. The technique uses ultra-short laser pulses and detectors sensitive to single photons.This work was performed in collaboration with the Laboratory of Theoretical Physics of Nanosystems at EPFL and Nicolas Sangouard at the Quantum Optics Theory Group in Basel.

Detecting the birth and death of a single phonon
Our latest results on single phonon Fock state generation are now published on the arXiv and were submitted for peer-review! This is the first direction demonstration that a single quantum of vibrational energy can be excited and prepared using a projective measurement on the quantum-correlated Stokes photon. This work was performed in collaboration with Dr. Vivishek Sudhir (...)
