Rigetti Computing’s novel chiplet approach has produced 36-qubit modules that consistently achieve 99.5% average single- and two-qubit gate fidelity in benchmark tests. This performance compares favorably to leading quantum hardware peers and represents a 0.3 percentage-point improvement over the company’s previous monolithic designs. By fabricating smaller, functionally complete units and interconnecting them via superconducting couplers, Rigetti has reduced fabrication defects by 20% and increased yield of working qubits per wafer by 35%. These advances validate the modular architecture that underpins its plan to scale to larger systems.

In the past six months Rigetti has signed a multi-year collaboration with the Air Force Research Laboratory to co-develop cryogenic control electronics optimized for high-density qubit arrays. Under the agreement, AFRL will contribute up to $15 million in research funding, while Rigetti will integrate the resulting microwave and RF components into its next-generation QCS systems. Concurrently, a joint software initiative with Nvidia will leverage CUDA-accelerated simulators to refine error-mitigation routines. Nvidia’s hardware support and software expertise are expected to cut quantum circuit compilation times by 40%, accelerating application development for enterprise clients.

Rigetti’s strategic roadmap targets deployment of a >1,000-qubit system by Q4 2027, building incrementally from its 36-qubit chiplets. The company plans to integrate up to 32 modules on a single cryostat, yielding an aggregate capacity exceeding 1,100 physical qubits. To manage cross-module communication, Rigetti has developed high-bandwidth interposers capable of preserving qubit coherence for up to 250 microseconds. Roadmap documents indicate calendar milestones for 128-qubit prototypes in late 2024, 512-qubit demonstrators in mid-2026 and full-scale systems by the end of 2027—positions that, if met, would keep Rigetti on pace with industry leaders in the race to practical quantum advantage.
