### Biography

**Profile**

Dominic Berry received his PhD from The University of Queensland in 2002. He was an ARC Postdoctoral Research Fellow from 2004 to 2006, and an ARC Future Fellow from 2011 to 2015. He also held postdoctoral positions at Macquarie University and the Institute for Quantum Computing (IQC). He is now a Senior Lecturer at Macquarie University. He is a member of the Australian Institute of Physics, American Physical Society, Optical Society of America, and Australian Optical Society.

Dominic Berry has an h-index of 29 (from Google Scholar), with over 3000 citations, and 552 citations just in 2017. He has more than 70 journal and conference publications, including work in Nature, Science, STOC, FOCS, Nature Photonics, Nature Nanotechnology, and Physical Review X. He teaches Quantum Information and Technology for Masters of Research students, as well as third-year General Relativity and Quantum Mechanics.

Research Interests

Dominic Berry has research interests in a wide range of areas in quantum information and quantum optics. He pioneered many advanced techniques for simulation of quantum systems on quantum computers. That is arguably the most important potential application of quantum computers, because it could enable the design of new materials and chemicals. He invented techniques for Hamiltonian simulation using higher-order product formulae in 2007, then techniques using quantum walks and linear combinations of unitaries in 2012-2015. He then applied these techniques to quantum chemistry in collaboration with researchers at Harvard and Google.

In the area of quantum optics Dr Berry has pioneered adaptive techniques for high-accuracy measurement of phase. Phase measurement is key to many forms of precision measurement. For example, gravitational wave detection is based on phase measurement. He invented techniques using nonclassical states to achieve the theoretical limit for measurement of a constant phase, as well as for measurement of a varying phase. As well as designing techniques for measurement of the phase in optics, he is applying his techniques to Nitrogen Vacancy centres for precision magnetometry, as well as phase measurement in quantum algorithms.
