Circuit quantum electrodynamics

Summary

Quantum electrodynamics is the fundamental theory describing photons, electrons and their interaction. What happens when an electronic circuit operate in the quantum regime such that currents and voltages behave according to the laws of quantum electrodynamics? What kind of technology becomes possible with this new "quantum electronics"?

Synopsis

When electrical circuits are cooled down to milli-Kelvin temperatures, the metal becomes superconducting and currents and voltages start to behave quantum mechanically. It is essentially a circuit realisation of quantum electrodynamics. This gives us an ideal playground for both exploring light-matter interaction at a very fundamental level, and developing new technology based on “quantum electronics.” In fact, this platform is arguably the most promising approach to quantum computing today, and several tech companies (e.g., Google, IBM and Rigetti Computing) have recently decided to invest heavily in this technology. In this theory project we will think outside the box and investigate new ways to both store and manipulate quantum information in superconducting quantum circuits. There are several possible student opportunities within this project, suitable for both undergrad and postgraduate level.

Additional Information

HDR Inherent Requirements

In addition to the academic requirements set out in the Science Postgraduate Handbook, you may be required to satisfy a number of inherent requirements to complete this degree. Example of inherent requirement may include:

- Confidential disclosure and registration of a disability that may hinder your performance in your degree;
- Confidential disclosure of a pre-existing or current medical condition that may hinder your performance in your degree (e.g. heart disease, pace-maker, significant immune suppression, diabetes, vertigo, etc.);
- Ability to perform independently and/or with minimal supervision;
- Ability to undertake certain physical tasks (e.g. heavy lifting);
- Ability to undertake observatory, sensory and communication tasks;
- Ability to spend time at remote sites (e.g. One Tree Island, Narrabri and Camden);
- Ability to work in confined spaces or at heights;
- Ability to operate heavy machinery (e.g. farming equipment);
- Hold or acquire an Australian driver’s licence;
- Hold a current scuba diving license;
- Hold a current Working with Children Check;
- Meet initial and ongoing immunisation requirements (e.g. Q-Fever, Vaccinia virus, Hepatitis, etc.)

You must consult with your nominated supervisor regarding any identified inherent requirements before completing your application.
