Professor Michelle Simmons has pioneered a radical new technology for creating atomic-scale devices, producing the first ever electronic devices in silicon where individual atoms are placed with atomic precision and shown to dictate device behaviour. Her groundbreaking achievements have opened a new frontier of research in computing and electronics globally. They have provided a platform for redesigning conventional transistors at the atomic scale and for developing a silicon-based quantum computer: a powerful new form of computing with the potential to transform information processing.
