In this talk we will describe progress towards large-scale, fault-tolerant quantum computing with photons. This talk will span materials innovations for high-performance photonics, improvements in photonic component performance with an emphasis on improved optical loss, prototype systems of entangled photonic qubits, qubit networking, and novel high-power cryogenic cooling solutions designed for future datacenter-scale quantum computers. We will show new prototype systems designed to progressively overcome the key challenges to scaling up photonic quantum computers. We will also give an overview of the architecture of fusion-based photonic quantum computers, describe near-term systems milestones, and give a view on the long-term roadmap to useful, fault-tolerant machines
Pete Shadbolt is a co-founder and Chief Scientific Officer at PsiQuantum. He has worked on quantum computing for the last 15 years. Pete has a PhD in experimental quantum photonics from the University of Bristol and completed a postdoc in the theory group at Imperial College in London. In 2016, Pete and his co-founders moved to Palo Alto, California to start PsiQuantum.
PsiQuantum’s only goal is to build and deploy a useful, fault-tolerant quantum computer. The company’s photonic approach allows it to leverage high-volume semiconductor manufacturing and existing cryogenic infrastructure to rapidly scale its systems. In 2024, PsiQuantum announced that it will build its first utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois.
