The quantum group at CPUT led by Prof. Kessie Govender and Mr Rory Pentz is focusing on the physics and applications of cold and ultra cold atoms.
Between 2016 and 2018 a cold atoms/quantum optics laboratory was established on the Bellville campus of CPUT. At present Rubidium atoms are cooled to micro-Kelvin temperatures using a system of laser beams that are precisely tuned to the correct wavelengths. The entire cooling process is undertaken in an ultra-high vacuum chamber. The next phase of the project is to undertake nonlinear laser-atoms interaction experiments using cold atoms to generate entangled photons and to study the basic physics of laser atom interactions. Further, the cold atoms setup is being upgraded to ultra-cool the atoms to nano-Kelvin temperatures to create and study Bose-Einstein Condensates (BEC).
Projects
- Generation of entangled photons using nonlinear optical processes in warm and cold atoms
- Development of a quantum key distribution system using entangled photons
