Introduction to Quantum Optics and Information Processing

A Masterclass with Professor Jason Twamley, Director, Quantum Machines Unit, Okinawa Institute for Science and Technology Graduate University, Japan

Quantum optics is the science of the quantum behaviour of bosonic modes (e.g. light, motion, collective-spin wave), and its interaction with matter. This has a long history and came way before quantum computing. Quantum optics underpins much of today’s fast growing quantum information revolution.

In this Masterclass we introduce the basic concepts of quantum optics, which include the quantum systems of a two-level system, optical/microwave cavity, cavity Quantum Electrodynamics and the famous Jaynes-Cummings model – a two-level atom interacting with a quanitzed electromagnetic mode, the Dicke/Tavis Cummings Model – where one has many two-level systems interacting with the quantized EM modes. We look at these systems theoretically and how they are implemented in a wide range of physical setups including optical and microwave cavities and motional/spin-wave setups. If time permits we will introduce some methods to simulate these models on any laptop and how they play central roles in today’s modern experiments in quantum technology.

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 in 2005, he accepted a call as the Professor of Quantum Information Science at Macquarie University in Sydney. 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 is currently 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.

Professor Twamley is a UWA Institute of Advanced Studies Visiting Fellow.
