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. Read the article in R&D magazine.
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.

Andrew was at the DST Innovation Bridge chatting to the Director General of the DST (Department of Science and Technology), Dr Phil Mjwara, and the Minister of Science, Naledi Pandor.
Established in 2015, the Innovation Bridge is an event aimed at encouraging and accelerating the use and commercialization of technologies and knowledge in publicly funded research and technology institutions.
Andrew will be talking about our work on quantum communication and encryption tomorrow morning at 7:50 AM SA time. See the article here and tune in or listen live to hear all about it!.
We are working on using patterns of light and quantum principals to send multiple amounts of data in a fundamentally secure way – a big step towards speeding up the internet and protecting against encryption weaknesses exploited by quantum computers. Article in Times Live.
