Dr. Valeria Rodriguez-Fajardo

Research Fellow

Valeria started developing her interest in photonics as a Physics undergraduate at the National University of Colombia. An interest that lead her to the National Institute of Astrophysics, Optics and Electronics (INAOE), Mexico, where she pursued a Master degree in Optics. She continued her career in Spain, where she conducted a PhD in photonics at ICFO – The Institute of Photonics Sciences. Through her career, she has doubled in different fields of optics, such as, holography, plasmonic trapping of micrometer-sized dielectric particles, spectroscopy, as well as, imaging of plasmonic nanoparticles immersed in complex environments (such as biological cells). Her main current interest is quantum imaging, where she can apply her knowledge to combine imaging techniques with quantum optics.

Dr. Najmeh Tabe Bordbar

Research Fellow

Najmeh obtained her Bsc and Msc in physics from Shiraz University, in Iran. She received her Ph.D in Quantum physics from Sharif University of Technology in 2017. She has introduced a constructive method for using separable states to distribute d-level Bell states between two parties and GHZ states between three and more parties. Besides, she has investigated the noise effects on the performance of entanglement distribution by separable state. One of her main objectives and interest is to put her theoretical findings into practice and to increase level of security in order to make it impossible for anyone to steal the information that is transmitted between (for example) Alice and Bob.

Most of all, he hopes to encourage more young Africans to take on science related careers and to join in on the second quantum revolution. “We are currently in the midst of a second quantum revolution.” Jonathan P. Dowling et. al.

Nicholas Bornman

PhD Student

Nicholas obtained his B.Sc. (Hons.) from the University of Pretoria. After completing an MSc at the University of the Witwatersrand (WITS), which looked into the su(2) and su(3) generators acting on restricted Schur polynomials, he was awarded a Perimeter Scholars International Scholarship to study theoretical physics at the Perimeter Institute in Canada. Upon completion of his second MSc, he returned home and is now pursuing his Ph.D. at WITS. It will look into higher-dimensional, multi-photon systems, as well as the interface between quantum field theory and quantum information.

Nokwazi Mphuthi

PhD Student

Nokwazi is PhD student with a Bsc in Land surveying from the University of KwaZulu natal. As part of her Msc project, she worked in a joint collaboration project with Hartebeesthoek Radio Astronomy Observatory (HartRAO), NASA and Observatoire de la Côte d’Azur(France) to develop the first Lunar Laser Ranging system in the Southern Hemisphere. She obtained her Msc, also in Land Surveying from the University of KwaZulu-Natal. As an extension of the LLR work, efforts were needed to increase the efficiency of the system. This paved the way to collaborations between the Structured Light lab and HartRAO. The project aims to improve increase the photon return rate of laser ranging systems using structured light and optimistically pave way for sending Orbital Angular Momentum to the Moon.
