Professor Buchler has extensive experience in quantum and nano-optics. Ben completed a PhD on the electro-optic control of quantum measurements in 2002 and took up a postdoctoral position at ETH Zurich working in the nano-optics group. During this time, he used near-field scanning probe techniques to characterise photonic crystal waveguides and cavities, as well as perform measurements of single-molecule fluorescence quantum efficiency.
Returning to the Australian National University in 2006, Ben became a Chief Investigator in the ARC Centre for Quantum-Atom Optics and began working on quantum memory based on warm atomic vapour. A source of squeezed light compatible with the atomic system was also developed, allowing experiments that probed the interaction of quantum entanglement with quantum memory. In 2010 Ben was awarded an ARC Future Fellowship to support his work in the Centre and in 2011 he was part of the ANU quantum memory team which was a finalist in the Eureka Awards.
Recent work has shown how machine learning can be used to improve the performance of quantum systems. This technology is now being deployed in other centre experiments, as well as being pursued as a commercialisation opportunity. Ben has published more than 90 refereed journal articles, including eight in the prestigious Nature suite of journals since 2009. His articles have attracted more than 3,800 citations.
