Professor David Jamieson, CQC²T Chief Investigator and Professor of Physics at the University of Melbourne, is one of five international researchers awarded a 2021 Royal Society Wolfson Visiting Fellowship.
The Royal Society Wolfson Visiting Fellowships enable leading international researchers and their host organisation to develop ongoing collaborative research links, share ideas and practice.
Prof Jamieson was awarded the Fellowship for his research on ‘Atomic qubits by ion implantation: towards very large-scale quantum devices’ in collaboration with the University of Manchester.
A quantum computer with a billion quantum bits (qubits) could have revolutionary potential for quantum mechanical drug design or discovering new pathways to fusion power. These capabilities are well beyond the capacity of even the most powerful classical computers. A quantum computer gets its revolutionary capabilities by using the strange laws of quantum mechanics to encode and process information using delicate quantum states programmed into the machine.
Taking inspiration from classical information technology Professor Jamieson will investigate the promising attributes of arrays of single donor atoms with large nuclear spins by implanting them into semiconductor chips. The quantum mechanical nuclear and electronic spins on these atoms in spin-free crystals can be configured with quantum states that are relatively insensitive to the external perturbations that shorten the lifetime of the programmed qubits. This work will address the challenge of finding pathways to building a very large-scale quantum computer device where robust logical qubits are encoded in clusters of atomic qubits.
