Abstract title: Photoacoustic, light-speed, and quantum imaging

Abstract resume:

Quantum technology will usher in world-changing capabilities only once scalable, fault-tolerant quantum systems emerge. In this talk I will discuss a few quantum system engineering design principles which directly follow from the single axiom that scalable fault-tolerant quantum systems will ultimately be modular in their construction to allow for unlimited horizontal scaling. Essentially, in this view [1], quantum networks and quantum computers ultimately can be seen as the same core technology. I will walk through the importance of the quantity and quality of quantum I/O, and how connectivity is the key to fault-tolerance as it unlocks highly efficient quantum LDPC error correcting codes. I then dive into how Photonic’s quantum computing and networking platform is competitively positioned to address these challenges and offer a scalable high-performing quantum system based upon the newly rediscovered T centre [2] which is the silicon colour centre that is the foundation of our system. It has zero-phonon optical transitions in the telecommunications bands, long-lived spins in their ground states, and can be integrated into silicon photonics chips at scale [3].
