US Department of Energy Releases National Quantum Roadmap Establishing 2028 Fault-Tolerance Milestones
The U.S. Department of Energy (DOE) has released its National Quantum Roadmap, aiming for error-corrected quantum computing by 2028. …
The U.S. Department of Energy (DOE) Office of Science Advisory Committee (SCAC) Quantum Subcommittee has published its comprehensive report, titled "SCAC Quantum Committee Report: Path to an Integrated Quantum Future." Chaired by Dr. Anna Grassellino (Fermilab) with Dr. Supratik Guha (Argonne National Laboratory / University of Chicago) as vice-chair, the national strategy establishes a science-first, milestone-driven roadmap targeting a scientifically relevant, error-corrected quantum computing capability by 2028.
The SCAC report mandates a fundamental metric shift across federal quantum investments: replacing physical qubit counts with demonstrated scientific utility. Rather than evaluating hardware solely through raw physical qubit numbers, federal research programs will measure progress by a system's capacity to execute intractable calculations across quantum chemistry, drug discovery, catalytic material design, fusion plasma simulation, and fundamental high-energy physics.
Aligned with the Administration's Quantum Genesis Initiative and the DOE Q Competition, the roadmap outlines a three-phased strategic framework designed to transition quantum processing units (QPUs) from isolated lab instruments into integrated co-processors across the DOE's high-performance computing (HPC) and artificial intelligence infrastructure:
[ DOE SCAC National Quantum Computing Strategy & Phased Execution Roadmap ] | ||
Implementation Phase | Core Mandate & Operational Structure | Strategic Objectives & Technical Deliverables |
• Phase I: Quantum Grand Challenges (2026–2028) | • Multidisciplinary competitive challenges • National Labs, university, and industry co-design | • Milestone-driven co-design of hardware, algorithms, and software to demonstrate error-corrected scientific utility by 2028 |
• Phase II: DOE Quantum Computing User Facility (QCUF) | • National open-access scientific user facility • On-premises co-located QPU hardware | • Replaces opaque "black-box" cloud APIs with open, co-developed control stacks, cryogenics, and hardware architectures |
• Phase III: Integrated Quantum Future (2030+) | • Ecosystem-wide technology integration • Hybrid Quantum-HPC-AI network integration | • Embeds quantum co-processors, simulators, and sensors into leadership supercomputers (Frontier, Aurora) and user facilities |
To preserve technological flexibility, the SCAC report emphasizes a modality-neutral stance, advocating for continued co-design investments across superconducting circuits, neutral atom arrays, trapped ions, photonics, and silicon spin qubits. Furthermore, the report recommends new partnership models to accelerate technology transfer, including 6-to-18-month embedded co-design fellowships, joint laboratory-industry personnel appointments, and open interconnect standards for hybrid classical-quantum software stacks.
