DARPA selects Microsoft for the final phase of its US2QC program for utility-scale quantum computers

Microsoft Quantum/Majorana topological qubits

DARPA selected Microsoft and PsiQuantum for the Validation and Co-Design stage of its US2QC program, part of the Quantum Benchmarking Initiative, which asks whether a quantum computer worth more than it costs can be built by 2033. More than 50 DARPA experts reviewed Microsoft's topological-qubit design.

• Microsoft using compact superconducting topological qubit architecture; PsiQuantum using silicon-based photonics.
• Over 50 independent experts reviewed both approaches since early 2023 covering technical strategy, fault tolerance, roadmaps, components, architecture.
• Additional companies selected for Stage A in early spring to present utility-scale concepts.
