Speaker: Dr Isaac Kim, University of Sydney
Isaac Kim is a Senior Lecturer at the University of Sydney. He works on quantum information theory and quantum computation and has worked at PsiQuantum, Stanford, IBM, Perimeter Institute prior to joining USYD.
In the near future, quantum computing researchers are expected to have access to quantum computers consisting of a few hundred qubits. Due to the absence of error correction, these near-term devices will not be reliable enough to carry out well-known textbook quantum algorithms such as Shor’s algorithm on a large scale. Can we do anything that is practically useful with these devices? I will argue that an important near-term application of a quantum computer would be the prediction of various physical properties of strongly interacting quantum many-body systems. We expect this to be possible because a quantum computer can significantly speed up the main bottleneck of the existing computational approach to study such systems. Moreover, the quantum part of the computation possesses an unusual form of resilience to the noise that is prevalent in near-term quantum computers. I will report on the ongoing progress in this research direction and discuss the future prospect of this program.
