Welcome

Welcome to the Quantum Information Group. This group is dedicated to the research in the field of quantum information and optics. We are part of the School of Chemistry and Physics at the University of KwaZulu-Natal.

Our research areas include the theory of quantum communication and quantum teleportation with spatial light modes. In this context, we search for convenient ways within quantum optics to combine the descriptions of the spatial degrees of freedom of light and the number of photons. We also study the possibilities to use Optics in Quantum Information Processing. For example, classical light can be used to detect atmospheric disturbance when communicating with single photons and correct resulting errors.

In addition, we design optical implementations of quantum walks and algorithms. One of the focus areas of the Quantum Information Group Konrad (QIGK) is Quantum Measurement and Control. Here, our expertise lies in the monitoring of the dynamics of quantum systems. We also look for efficient ways to drive quantum systems, such as trapped ions, into target states and target dynamics. Recently, we have discovered a new class of coherent feedback control schemes, which is based on interaction rather than measurement. Another QIGK research topic is the foundations of Q.M, for example so-called Bell Tests and macroscopic quantum effects.
