Magneto-quantum-mechanics: engineering of macroscopic quantum states using magnetic forces

Abstract: The creation of macroscopic quantum states of massive systems allows one to begin to explore the boundaries between the classical and quantum worlds and, in particular, how gravity may interface with quantum mechanics. In this talk I will discuss our recent theory and experiments on engineering massive (milligram), objects into quantum states of motion, e.g ground states and Schrodinger cat states. We explore how spin-mechanical coupling can be demonstrated in massive quantum systems and how to use such a coupling to engineer quantum engines.

Bio: Professor Jason Twamley is a researcher in the 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 in 2005, he accepted a call as the Professor of Quantum Information Science at Macquarie University in Sydney, Australia.  He 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). During that period he 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. He conceived of a new field of quantum technology: quantum magneto-mechanics where one uses magnetic fields for levitating and trapping quantum objects. He currently is the director of the Quantum Machines Unit at the Okinawa Institute for Science and Technology Graduate University, Japan, which performs research (both theoretical and experimental), on the development of hybrid quantum machines for sensing, communication and computing.
