Professor Jason Twamley is a leading researcher in the theoretical physics of quantum science and technology with a particular emphasis on hybrid quantum systems – systems where one marries together different types of quantum systems to achieve an overall functionality which no one subsystem possesses. Professor Twamley originally trained as a lecturer in Ireland and there pioneered many European Union projects focusing on fullerene and diamond based quantum technologies and won a number of EU STREPS and Integrated Projects.

Since 2005, Professor Twamley has worked at Macquarie University as the Professor of Quantum Information Science and has developed expertise in superconducting, diamond, nanomechanical, magnetic and atomic quantum technologies. His particular focus is on developing quantum sensors where quantum effects can provide society with more precise and functional sensors for use in a variety of settings, examples being magnetometers and inertial sensors. Together with Associate Professor Gavin Brennen he conceived of a new field of quantum technology: quantum magneto-mechanics where one uses magnetic fields for levitating and trapping quantum objects. 

Professor Twamley has strong research collaborations with Germany and the diamond research groups of Prof Jelezko and Wrachtrup, and in China with the groups of Profs Peng Xue and Mang Feng.

Mentoring and Research Training Track Record

Professor Twamley has trained to date approx. 10 postdoctoral researchers, 9 PhD students, 5 Master of Science and 5 Honours students. His students have gone on to careers in academia as lecturers and professors, and into industry primarily finance, IT and geophysical informatics. Professor Twamley’s approach to training aims to help progress students and researchers to become independent, inquisitive and critical thinkers. The reward of discovery comes from  the acquiring of deep understanding and then coming to a solution of a novel problem that has the potential to advance our knowledge in science. 

Quantum opto-magnetomechanical interface between distant superconducting chips

Grand challenge: Develop design principles for robust control of hybrid quantum systems and demonstrate their utility in experimental applications.

EQuS researchers have developed a theoretical design allowing superconducting quantum chips to communicate quantum mechanically to each other over large distances through an optical fibre. If achieved, this would allow long distance quantum entanglement or teleportation – both key steps towards building a truly global quantum internet via a quantum repeater. Devised by Dr Keyu Xia and Professor Jason Twamley from the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) at Macquarie University, and Dr Michael Vanner at the University of Queensland, this work makes use of the tiny magnetic fields generated by superconducting quantum chips to alter the properties of an optical cavity, via a agnetostrictive material. A material that is “magnetostrictive” physically expands in the presence of a magnetic field. By using this novel property, this project was able to show how the magnetic fields from a superconducting quantum chip can effectively transmit and receive via a connected optical cavity and optical fibre through to a distant superconducting chip in another laboratory elsewhere.
