Terry Rudolph is a co-founder and Chief Architect at PsiQuantum. Terry did his PhD in theoretical quantum optics, and held positions at the University of Toronto and Bell Labs before moving to Imperial College in 2003 where he became Professor of Quantum Physics in 2011. In the period 2004-2015 he wrote four academic papers founding a theoretical approach to photonic quantum computing that forms the basis from which PsiQuantum’s current architecture has been further developed. He also founded and then co-Directed for 7 years the UK’s first Centre for Doctoral Training, which graduated over 130 PhD students in the field of quantum information. His research receives more than 1000 citations per year.
Presentation Title: PsiQuantum: How to build a photonic quantum computer and how to use it
Abstract: PsiQuantum intends to deploy the world’s first useful-scale quantum computer in Australia. The overhead of error correction means that such a machine needs millions of physical qubits to be able to do computations with a few hundred logical qubits. I will discuss what’s required to build such a machine, which has necessitated PsiQuantum fabricating and networking devices on scales from the Angstrom to the kilometer, and how it all comes together. I will provide an introduction to how a quantum computer is used. I’ll also overview recent improvements in quantum algorithms that allows us to identify which applications will be relevant to early quantum computers, and which ones will need to wait for later generations of machines.
