The postponement allows for additional testing and a new chip iteration to address tunable coupler complexities and improve two-qubit gate fidelity toward a 99.5% median target. The company currently reports 99% median two-qubit gate fidelity on the 108-qubit system, with higher fidelities of 99.7% and 99.6% on smaller 9-qubit and 36-qubit systems respectively. The Cepheus-1-108Q uses a modular architecture with twelve 9-qubit chiplets and will be Rigetti's highest qubit count system. ## Full article daily.dev links to this article rather than hosting it.
