We recently visited HartRoa, just outside Johannesburg, SA where space geodesy and astrophysics are the topics of the day – everyday. Here, amongst many other exciting projects, they work with large telescopes to do radiometry, use satellite laser ranging to track satellites and feed into the databases that gives us accurate GPS.
See the article in Business Day as they look into the progress of quantum communications and cryptography, highlighting the contributions of our group throughout 2017 in helping drive quantum technologies as the year comes to an end.
Hend Sroor won the best poster award at the recent OSA Siegman School for Lasers. Nicknamed ‘fractal lady’ after the winning research topic, Hend made it to the top amongst the ~100 students attending the conference from around the world and presenting their research in poster format.
We have demonstrated the use of over 100 patterns of light in an optical communication link with some of our collaborators – this will potentially increase the bandwidth of communication systems by 100 times, pushing back the fast-approaching bandwidth limit in this information age.

Alongside Prof. Jonathan Leach, we have shown that previously independent photons can be entangled without interaction occurring between them for multiple states of twisted light – another leap forward in high-bandwidth, secure quantum communications.
