Overview
- Rigetti made its Cepheus-1-108Q system available to paying users through AWS’s Amazon Braket and the company’s own cloud platform.
- The machine reports 99.1% median two-qubit gate fidelity, a measure of how often paired-qubit operations run correctly, with management targeting 99.5% later in 2026, while some outlets cited a separate 99.9% figure tied to smaller prototypes.
- Built with a modular multi-chip design, the 108-qubit platform triples Rigetti’s prior 36-qubit capacity and is described as the largest modular multi-chip quantum computer now on the market.
- Investors bid the shares up by about 10% on the launch, and Benchmark and Mizuho kept positive ratings even as both firms cut their price targets.
- Rigetti outlined up to $100 million for a U.K. build aiming for a system with more than 1,000 qubits in three to four years, and it sold a nine-qubit Novera unit to the University of Saskatchewan for on-campus research.
