Rigetti Computing announces general availability of 108-qubit system Cepheus-1-108Q
Rigetti Computing, Inc.
- Cepheus-1-108Q is Rigetti's highest qubit-count system, with twelve interconnected 9-qubit chiplets.
- System performs at 99.1% median two-qubit gate fidelity and 99.9% median single-gate fidelity with ~60 ns gate speed.
- Available via Rigetti Quantum Cloud Services and on Amazon Braket, as first gate-based device over 100 qubits.
- Rigetti plans to improve two-qubit fidelity to 99.5% later in 2026 and update roadmap toward quantum advantage in ~3 years.
- CEO Dr. Subodh Kulkarni states the chiplet-based architecture validates scaling approach for fault-tolerant quantum computing.
