Silicon-carbide modulator overcomes decades long 'missing block'

A collaboration with Harvard University has led to the development of a new-generation electro-optic modulator that could stamp out its bulky predecessor through the creation of a smaller, stronger, cooler, faster and cost-effective ...

Coughing downward reduces spread of respiratory droplets: study

With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling ...

Can defects turn inert materials into useful, active ones?

Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of applications, according ...

Fast tool developed for quantum computing and communication

Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the hidden structures of quantum entangled states. The study ...

Observing quantum coherence from photons scattered in free-space

Quantum coherence is a key ingredient of many fundamental tests and applications in quantum technology, including quantum communication, imaging, computing, sensing and metrology. However, the transfer of quantum coherence ...
