Fault-Tolerant Quantum Computing System Architecture Design

The contract seeks the development of high-level system architectures for fault-tolerant quantum computing systems capable of scaling to between 150 and 250 logical qubits by 2028, with a stringent requirement of achieving a logical error rate no higher than 10⁻⁸ per operation. This effort is focused on designing robust, scalable frameworks that integrate error correction, qubit control, and system-level redundancy to enable reliable quantum computation at scale. The architecture must account for physical hardware constraints, control infrastructure, and communication pathways between qubit modules while ensuring the overall system remains viable for industrial and scientific deployment. The solicitation, issued under NAICS code 541511 by the Department of Energy’s Oak Ridge Office, is classified as a subcontract and requires proposals to be submitted by June 10, 2026. Performance under this contract is expected to be conducted at a federal facility with a zip code of 20585, suggesting alignment with a government research center or national laboratory. The initiative is time-bound, with a clear technological milestone set for 2028, and demands innovative approaches to quantum error suppression and system integration that go beyond current state-of-the-art capabilities. This effort represents a critical step toward practical quantum computing with industrial-grade reliability.
