Michelle Simmons

Michelle Simmons. A pioneering physicist and entrepreneur, she is a global leader in the field of quantum computing and nanoscience. As the founder and director of the ARC Centre of Excellence for Quantum Computation and Communication Technology at the University of New South Wales, her work focuses on creating quantum computer components at the atomic scale. Her groundbreaking research has positioned Australia at the forefront of the international race to build a silicon-based quantum computer.

Early life and education

Born in London, she demonstrated an early aptitude for the sciences. She pursued her higher education at Durham University, where she completed a Bachelor of Science degree in physics. Remaining at Durham University for her doctoral studies, she earned a PhD in physics, specializing in the electronic properties of low-dimensional systems. Her postgraduate research laid a critical foundation for her future work in manipulating matter at the nanoscale, a field that would later converge with the emerging discipline of quantum information science.

Career and research

Following her PhD, she held a research fellowship at the University of Cambridge before relocating to Australia to join the University of New South Wales. In 2000, she established what would become a world-leading effort in atomic electronics. Her team at the University of New South Wales achieved a series of landmark firsts, including creating the world's first single-atom transistor and the narrowest conducting dopant wires in silicon. This research is central to the development of a quantum processor using phosphorus atoms embedded in silicon, a approach seen as a promising pathway to scalable quantum computation. In 2017, she founded the quantum computing startup Silicon Quantum Computing Pty Ltd, aiming to commercialize technology developed at the ARC Centre of Excellence.

Awards and honours

Her contributions have been recognized with numerous national and international accolades. She was appointed an Officer of the Order of Australia in 2012 and elevated to Companion of the Order of Australia in 2023. In 2018, she was named the Australian of the Year. Her scientific peers elected her as a Fellow of the Royal Society and a Fellow of the Australian Academy of Science. She has also received prestigious awards such as the Feynman Prize in Nanotechnology, the Kavli Prize in Nanoscience, and the Prime Minister's Prize for Science. In 2021, she was appointed as the first chair of the National Quantum Advisory Committee by the Australian Government.

Personal life

She is married to Thomas Barlow, a noted policy advisor and writer on innovation. Together they have three children. An advocate for STEM education and gender equity in science, she has spoken frequently on the importance of encouraging more women into physics and engineering. She maintains strong collaborative ties with leading international institutions, including Delft University of Technology and the University of Wisconsin–Madison, while being a prominent figure in the scientific community of Sydney.

Legacy and impact

Her legacy is defined by establishing a dominant Australian capability in the global quantum technology sector. By proving that quantum bits can be engineered with atomic precision in silicon, she has fundamentally shaped the roadmap for building a practical quantum computer. Her leadership of the ARC Centre of Excellence has trained a generation of scientists and engineers, creating a skilled workforce for the burgeoning quantum industry. Through Silicon Quantum Computing Pty Ltd, she continues to drive the translation of academic research into a commercially viable technology, aiming to secure Australia's strategic position in the second quantum revolution.
