The Road to Large-Scale Fault-Tolerant Quantum Computers
DescriptionNeutral-atom quantum computing presents a compelling path toward scalable, fault-tolerant systems, with advantages in qubit count, reconfigurable connectivity, and manufacturability. This presentation details QuEra’s roadmap from today’s processors toward large-scale error-corrected architectures capable of deep integration with high performance computing (HPC) environments. We outline progress in increasing physical qubit numbers, implementing mid-circuit measurement and feed-forward, and developing modular architectures for millions of qubits. Emphasis will be placed on resource estimates for logical qubits, error-correction overheads, and co-design approaches that align quantum hardware evolution with HPC workflows. By exploring use cases in quantum simulation, optimization, and machine learning, we highlight how fault-tolerant quantum systems can augment classical supercomputers, accelerating solutions to problems beyond classical reach. The talk will map a technically credible path from today’s systems to tomorrow’s exascale-class quantum-HPC hybrid platforms.
