Complexity at small scales with Circuit QED Quantum Simulators

Overview:

In the field of quantum simulations, research into the behaviour of complex, interacting systems is driven by applications in areas like quantum chemistry and condensed matter physics, where near-future quantum processors will find their first real-world applications. In this project, we aim to study these behaviours using small-scale experimental quantum simulators based on superconducting circuit quantum electrodynamics (circuit QED).

Circuit QED systems based on nanofabricated superconducting quantum circuits are among the most promising quantum information processing platforms, with major quantum computing efforts from global tech companies like Intel, IBM and Google. Here, by studying circuit QED simulators that achieve complexity at small scales, we will learn how to address challenges that will face more general circuit QED simulation platforms as they scale up in size and complexity.

We are seeking talented, motivated and versatile PhD candidates who would thrive in a supportive, collaborative research environment. The successful candidates will join project supervisor, Senior Lecturer and ARC Future Fellow Dr Nathan Langford, to help build an exciting, dynamic new research team at University of Technology Sydney (UTS) in a purpose-built, state-of-the-art new circuit QED facility. In a young group, candidates will also use their own creativity to help shape future research directions.

Under Dr Langford’s guidance, the candidates will develop the broad range of experimental and theoretical skills necessary for this demanding research field, from sample design and fabrication, cryogenics and microwave measurements, to quantum theory and numerical modelling. Fabrication access will be provided through state-of-the-art nearby national facilities when not available on campus. In addition to developing expertise in a highly competitive international research field, the candidates will build strong skills in communicating and presenting their results to the national and international research community in journal publications and conferences.
