Cheltenham Science Festival is one of the UKs largest public engagement science exhibitions, which has had attendance of 45,000 visitors at previous events. This year’s festival saw researchers from QETLabs showcasing a variety of demonstrations.

QET Labs students and researchers Henry Semenenko and Alasdair Price organised demonstrations ranging from explaining the fundamental properties of light such as polarisation, and how we use it in sunglasses and 3D cinema glasses, to addressing current affairs of hacking encrypted messages and securing communications against malicious adversaries.

The exhibit was well received, engaged with a large number of people and was popular with schools, children and adults from all types of non-technical backgrounds. Many were interested in how optics and quantum technologies work and how it will impact their lives in the near future.
