Dr Danni Holmes uses a special single-atom gun to implant “donor” atoms into silicon chips for quantum technology.

Working at atomic scales has its challenges — even a sneeze in a cleanroom can derail weeks of effort! Danni is an excellent communicator, and her most unusual science outreach gig was doing live experiments over Antarctica. She will soon be touring Australia for the Marie Curie Lectures as part of an award from the Australian Institute of Physics. Danni shares a teaser: quantum science isn’t just about tiny particles, but about everything from why stars shine to how quantum computing might reshape our society in the decades ahead.

Ever wondered how the tiny processors in your phone or laptop are made? It all comes down to an ancient idea—writing on stone—taken to the most extreme level imaginable.

Elliot Cheng is a Specialist Engineer in Nanolithography (aka tiny-stone-writing) at the University of Queensland’s Centre for Microscopy and Microanalysis. Using electron beams and extreme ultraviolet (EUV) lasers, he "prints" some of the smallest patterns in the world. This cutting-edge tech relies on quantum science and underpins the powerful, tiny computers we use every day.
