Magnetic engineered quantum systems for sensing and fundamental studies


Many types of quantum systems use mechanical degrees of freedom – and to achieve low decoherence rates researchers have developed a number of ways to levitate quantum systems using either optical forces (optical tweezers), or electro-dynamic forces (ion traps). We have proposed and developed an alternate route using magnetic levitation – which uses no active power and can support macroscopic objects. We discuss some research relating to magnetic trapping and cooling or macroscopic objects, both theory and experiment. We talk about using mechanical degrees of freedom to store quantum information for long periods of time.

Professor Jason Twamley

Professor Jason Twamley is a 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. In 2005, he was appointed as the Professor of Quantum Information Science at Macquarie University in Sydney, Australia, and took part in the national efforts there to develop quantum computation and quantum technologies in the Australian Research Council Centers of Excellence in Quantum Computer Technology (CQCT), and Engineered Quantum Systems (EQUS). In 2020 he joined the Okinawa Institute for Science and Technology (OIST) Graduate University in Japan where he currently heads a research team developing Quantum Machines both theoretically and experimentally.
