Rigetti Computing Announces a Delay in the General Availability of Its Cepheus-1-108Q Processor An Assembed Cepheus-1-36Q Processor Demonstrating the Company’s Multi-Chip Technology Rigeiti’s Cepheus-1-108Q processor is a 108 qubit machine consisting of 12 nine-qubit modules. It can be thought of as the extension of the company’s previous Cepheus-1-36Q processor which is composed of four nine-qubit modules that was deployed in August of last year. Although the company originally had the goal of making this larger version available by the end of 2025, the company has delayed this until around the end of Q1 2026 in order to further improve the median two-qubit gate fidelity to the 99.5% level. The company indicated that it this metric is currently at 99% for this 108 qubit system, 99.6% for the Cepheus-1-36Q system, and 99.7% for their nine qubit system. Rigetti has been a pioneer in providing quantum processors based upon a multi-module architecture. A press release with additional details can be viewed on the Rigetti website here.
