This is a prestigious research position, within a dynamic and highly collaborative international research environment. The role is based at Silicon Quantum Computing Pty Ltd, a start-up company attached to the headquarters of the Centre of Excellence for Quantum Computation and Communication Technology at the University of New South Wales in Sydney, Australia. The company is a unique start-up, being a public-private partnership between industry, government and UNSW Sydney that seeks to commercialise silicon quantum computing technology being developed in Australia – technology that has the potential to revolutionise computing worldwide.

The position is in a team working towards a prototype quantum processor assembled from donor-based spin qubits in silicon. The team, headed by Professor Andrea Morello, has made several landmark demonstrations towards this goal over the past five years, including the world’s first single-atom spin qubit in silicon and single-qubit gate fidelities amongst the highest for any solid-state qubit.

The successful candidate will develop and characterise devices that demonstrate a novel mechanism for donor-based two-qubit gates via medium-range dipole interactions with the overarching project goal of producing the prototype silicon quantum processor.

This is one of more than 20 positions currently open for applications. View the full list of available roles.
