Episode notes
Keep Iterating Hardware Rapidly
- Treat quantum systems as continuously evolving hardware: upgrade processors and control electronics regularly to push capability.
- Use a service model to give students and researchers access while iterating hardware every months.
Roadmap To Fault Tolerance
- IBM demonstrated a quantum workload in 2023 that could not be simulated classically and targets a fault-tolerant machine by 2029.
- Fault tolerance will open scientifically useful problems like molecular simulation and large optimization tasks.
Modular Error Correction Strategy
- Build modular error-corrected modules first, then link modules and scale those networks to reach large fault-tolerant systems.
- Focus engineering on making ~1,000-qubit modules and then connecting them into larger machines.
