Marcus completed his Ph.D. and Bachelor degrees in Engineering and Science at the University of Melbourne. He joined the Australian National University in 2012 as a postdoctoral fellow within the Solid State Spectroscopy group of the Laser Physics Centre. He has continued in this role and, despite his early career status, now leads the Diamond Quantum Science and Technology research program of the Laser Physics Centre.
Marcus is internationally recognised as a principal contributor to the emergence of diamond-based quantum technologies, including quantum microscopy, quantum computing and quantum communications. These technologies represent new paradigms of microscopy, computing and communications that have the potential to revolutionise many disciplines of science and technology.
Marcus’ research is characterised by the application of first-principles understanding of optical defects in diamond to the innovation of quantum technologies. In his Ph.D. thesis, Marcus developed the first self-consistent theory of the nitrogen-vacancy (NV) colour centre in diamond, which is a model system for many quantum technologies. Marcus’ theory resolved issues that limited the performance of the NV centre at the time and is the basis for the ongoing innovation of NV technologies and the growing effort to systematically identify similar optical defects. For this significant contribution, Marcus was awarded the University of Melbourne Chancellor's Prize for Excellence in the PhD thesis and a nomination for the Bragg Gold Medal of the Australian Institute of Physics.
As a postdoctoral fellow, Marcus continued innovating quantum technologies and has expanded his research to explore optical defects in various materials. In particular, Marcus collaborated extensively with leading groups around the world in order to realise his innovations. These include demonstrations of high-sensitivity nanoscale piezometry and vector electrometry. The former is currently the most sensitive high-pressure piezometry technique, which offers new means to study high pressure phenomena, such as superconducting and ferroelectric phase transitions. The latter is currently the most sensitive electrometry technique at room temperature, unique in its capability to measure the complete vector of an electric field and locate a single elementary charge with nanometre resolution. Marcus’ fundamental studies of the effects of temperature on the NV centre led to spin resonance and all-optical nanothermometry techniques suitable for biomedical applications, such as thermoablative cancer therapy. For these significant contributions and others, Marcus received several Early Career Awards, including the Ruby-Payne Scott Award of the Australian Institute of Physics, Geoff Opat Award of the Australian Optical Society, the Dr Phillip Law AC Award of the Royal Society of Victoria and runner-up to the New Journal of Physics Early Career Award.
Marcus’ primary research interest is the innovation of solid-state quantum technologies. In particular, technologies based upon the remarkable properties of optical defects in diamond and related materials.
His current research pursues three parallel programs:
The activities of these programs span from first-principles defect theory and modelling to the design and demonstration of quantum devices.
