Professor Simmons is Director of the Centre of Excellence for Quantum Computation and Communication Technology and an Australian Research Council Laureate Fellow. She has pioneered unique technologies internationally to build electronic devices in silicon at the atomic scale, including the world's smallest transistor, the narrowest conducting wires, 3D atomic electronics and the first two qubit gate using atom-based qubits in silicon. As founder of Silicon Quantum Computing Pty Ltd, her team is at the forefront of developing a silicon-based quantum computer. Michelle is one of a handful of researchers in Australia to have twice received an Australian Research Council Federation Fellowship and now a Laureate Fellowship. She is a Fellow of the Royal Society of London, the American Academy of Arts and Science, the American Association of the Advancement of Science, the UK Institute of Physics, the Australian Academy of Technology and Engineering and the Australian Academy of Science.

In 2018 Professor Simmons was named Australian of the Year, one of the nation’s pre-eminent awards.

The atomic electronics research led by Professor Michelle Y. Simmons has the ultimate goal of developing a scalable, phosphorus in silicon, quantum processor. Professor Simmons’s group leads the field internationally in making precision atomic electronic devices in silicon for both conventional and quantum computing. Using a combination of scanning tunneling microscopy and molecular beam epitaxy phosphorus dopant atoms are controllably placed in Si devices with atomic precision. This has led to the development of the narrowest conducting wires in silicon, the development of the smallest precision transistors, the first two qubit gate between atom qubits in silicon and more complex architectures towards error correction. This ambitious program is currently developing all the functional elements for an error corrected scalable spin-based quantum computer, including techniques for multiplexed parallel qubit addressability, 3D atomic precision patterning, fast gate-based read-out, and both error detection and correction.
