Royal Society Summer Science Exhibition

The Royal Society Summer Science Exhibition is one of the largest events in the outreach calendar and is attended by thousands. Scientists from all over the UK are invited to display their cutting-edge research during the week-long event. After a competitive application process, the Centre for Quantum Photonics was invited to explain the weird and wonderful world of quantum computing, as one of only 22 exhibits.

Our exhibit took the public on journey to discover how we control light, why we want to use it to create more powerful computers and how the strange world of quantum mechanics will get us there. The first part of the display illustrated how our technology relies on the same physical processes as superfast broadband, confining light using total internal reflection.

We then demonstrated how quantum mechanics can explore problems in unfamiliar ways. By using a Galton box, we showed how quantum particles will take different routes to those we'd normally expect. By using these …
