Advancing Biological Imaging and Sensing Using Quantum Technologies with Warwick Bowen.

Quantum technologies can exponentially accelerate computer simulations and detect signals that would be invisible to other technologies. This provides the potential for wide impact across the biosciences: better modelling of biochemical processes, and better imaging of biological systems. In this talk I will provide an overview of this potential, and how it could create a new field of quantum biotechnology. As an illustrative example, I will then introduce work in my laboratory that uses quantum correlated light to enhance bioimaging. In that work, we demonstrate for the first time that quantum correlations can be used to evade photochemical intrusion on the biological specimen, and therefore to observe biological structures that would be otherwise inaccessible. We achieve this in a coherent Raman microscope, providing chemically-specific information about the cell. Our results represents the first demonstration of absolute quantum advantage in biological microscopy, and we hope will open the door to a bright future for quantum bioimaging.

Professor Bowen’s research focuses on the implications of quantum science on precision measurement, and applications of quantum measurement in areas ranging from quantum condensed matter physics to the biosciences. He is the Director of the just announced Australian Research Council Centre of Excellence in Quantum Biotechnology. He is also a Fellow of the Australian Institute of Physics, Director of the University of Queensland Precision Technologies Translation Hub, and a Theme Leader of the Australian Centre for Engineered Quantum Systems. Prof Bowen’s research is supported by the Australian Research Council, the US Air Force Office of Scientific Research, Lockheed Martin, the US Army Research Office and the Australian Defence Science and Technology Group.
