Rigetti Computing’s modular chiplet approach has delivered its first 36-qubit units with gate fidelity of 99.5%, marking a material improvement over its prior all-in-one monolithic chips. By assembling smaller, validated qubit blocks on a shared cryogenic interposer, Rigetti reduces defect rates during fabrication and enables parallel yield testing. Company engineers report that this strategy shortens development cycles by roughly 30%, supporting an ambitious plan to field a 1,000-plus-qubit system by the end of 2027. Internal roadmaps show quarterly scale-ups of 50 to 100 qubits per release, with reliability benchmarks now exceeding 98% for multi-chiplet assemblies.

Rigetti stock rose 45.2% during the 2025 calendar year and has continued to climb through early 2026, powered by two cornerstone collaborations. In Q4 2025, Rigetti sealed a multi-year agreement with the U.S. Air Force Research Laboratory to develop ruggedized quantum processors for electromagnetic spectrum operations. In parallel, a software-and-hardware integration pact with Nvidia, announced in January 2026, grants Rigetti access to Nvidia’s CUDA-accelerated simulation platform and GPU-based error-mitigation toolkits. Together, these partnerships underpin a projected 60% increase in quantum-computing service revenues in fiscal 2026, as Rigetti scales its cloud-based QPU offerings to government and commercial research labs.
