 ## Description

Rigetti Computing’s modular quantum processors scale to large qubit counts by interconnecting high fidelity, small scale superconducting quantum devices via inter-chip tunable couplers. In this talk, Andrew Bestwick will discuss Rigetti’s progress in building and integrating such QPUs by scaling chiplets laterally, allowing for steady manufacturing yield and good performance up to very large systems. Dr Betswick will conclude with Rigetti’s roadmap toward fault-tolerance with this architecture
