Scaling a chiplet-based quantum processor toward fault-tolerance

By Andrew Bestwick, Rigetti Computing

Rigetti Computing's modular quantum processors scale to large qubit counts by interconnecting high fidelity, small scale superconducting quantum devices via intra-chip tunable couplers. In this talk, I 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. I will conclude with Rigetti's roadmap toward fault-tolerance with this architecture.
