Reference excerpt

Michelle Yvonne Simmons (born 14 July 1967) is an Australian quantum physicist, recognised for her foundational contributions to the field of atomic electronics. She is the CEO and Founder of Silicon Quantum Computing. She is founding director of the Australian Research Council's Centre of Excellence for Quantum Computation & Communication Technology, and as of 2023 is Scientia Professor of Quantum Physics in the Faculty of Science at the University of New South Wales. She has twice been an Australian Research Council Federation Fellow, and is an Australian Research Council Laureate Fellow. In January 2018, Simmons was named Australian of the Year for her work and dedication to quantum information science, and in June 2019, she was appointed an Officer of the Order of Australia in the Queen's Birthday Honours in recognition of her "distinguished service to science education as a leader in quantum and atomic electronics, and as a role model".

Early life and education Simmons was born on 14 July 1967 in London, to a mother who worked as a bank manager and a father who worked as a policeman. Simmons grew up in South-East London with an older brother. Between 1985 and 1988 she undertook her undergraduate degree at Trevelyan College, Durham University, where she studied physics and chemistry of materials. As a postgraduate at St Aidan's College, Durham she was awarded a PhD in 1992 for her thesis "The characterisation of CdTe-based epitaxial solar cell structures fabricated by MOVPE", with research supervised by Andrew W. Brinkman.

Career and research From 1992 to 1998 Simmons worked as a research fellow in quantum electronics with Michael Pepper at the Cavendish Laboratory in the UK, where she gained an international reputation for her work in the discovery of the 0.7 feature and the development of 'hole' transistors. In 1999, she was awarded an Australian Research Council (ARC) QEII Fellowship and went to Australia, conducting research for four years under this fellowship. She was a founding member of the ARC Centre of Excellence for Quantum Computer Technology, and as of 2023 remains director of the centre. Simmons founded Silicon Quantum Computing, a Sydney based quantum computing company, in 2017 and is the current CEO. She has held several other positions over the course of her career, including:

2000: Director, Atomic Fabrication Facility, UNSW 2000: Manager, Atomic Fabrication and Crystal Growth Program, Centre for Quantum Computer Technology, School of Physics, UNSW 2003: Chair, New South Wales Branch, Australian Institute of Physics 2003: Member, C8 Commission, International Union of Pure and Applied Physics 2003: Australian Representative for Nanotechnology, International Union for Vacuum Science, Technique and Applications 2005: Member, Expert Advisory Committee for Physics, Chemistry and Geosciences, Australian Research Council 2007: Associate editor, IEEE Journal of Nanotechnology 2007: Chair, National Committee for Physics, Australian Academy of Science As of 2023 Simmons is Scientia Professor of Quantum Physics in the Faculty of Science at the University of New South Wales. In 2025 Simmons was elected to the Board of Directors of the Tech Council of Australia.

Achievements Simmons is well-known internationally for creating the field of atomic electronics, that is, building electronic devices at the atomic scale. Her research team at ARC created the first precision single atom transistor and the narrowest conducting wires in silicon, among other achievements. Since 2000 she has established a large research group dedicated to the fabrication of atomic scale devices in silicon and germanium using the atomic precision of scanning tunnelling microscopy. Her research group is the only group worldwide that can create atomically precise devices in silicon—they were also the first team in the world to develop a working "perfect" single-atom transistor and the narrowest conducting doped wires in silicon.

Publications and other activities

Simmons has published over 450 peer-reviewed journal papers, amassing over 13,000 citations, written five book chapters, and published a book on nanotechnology. She has also filed 44 patents and delivered over 400 invited and plenary presentations at international conferences. She was the inaugural editor-in-chief of npj Quantum Information, an academic journal publishing articles in the emerging field of quantum information science launched in 2015. She gave the Australia Day address for New South Wales in 2017, in which she spoke about the importance of setting high expectations for students. Simmons delivered the 2023 Boyer Lecture in four parts, titled The Atomic Revolution.

Worked examples

Example 1 — a first encounter with Michelle Simmons

Start with the simplest possible case. Write down what Michelle Simmons claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Michelle Simmons before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Michelle Simmons ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Michelle Simmons

In research: Michelle Simmons appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Michelle Simmons in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Michelle Simmons is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, 21st-century British women scientists, Academic staff of the University of New South Wales, so understanding it makes those chapters shorter.
In everyday life: Look for Michelle Simmons outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
