Rigetti delays Cepheus-1-108Q availability while reporting higher gate fidelities across its quantum systems.

Rigetti Computing, Inc. has adjusted its roadmap by moving general availability of its 108-qubit Cepheus-1-108Q system to around the end of the first quarter of 2026. For a hardware-focused quantum company, the timing of new system availability can influence when customers gain access to more capable processors and when related revenue opportunities may develop, though no financial figures are given here.

At the same time, the company reports technical progress, achieving median two-qubit gate fidelities of 99% on the 108-qubit system, 99.7% on its 9-qubit system, and 99.6% on its 36-qubit system. Higher gate fidelity generally means fewer errors in quantum operations, which can make systems more useful for practical workloads. The net effect of combining a launch delay with better performance metrics is mixed and depends on how customers value immediate access versus improved quality.
