Rigetti Launches 108-Qubit Quantum Computing System Cepheus-1-108Q

Rigetti Computing has made its 108-qubit quantum computing system, Cepheus-1-108Q, generally available. This system, the largest modular quantum computing setup in the industry, includes twelve interconnected 9-qubit chiplets.

This marks a significant increase from the previous 36-qubit system, Cepheus-1-36Q, tripling both the qubit and chiplet counts. Performance metrics show a median two-qubit gate fidelity of 99.1% and a median single-gate fidelity of 99.9%, with a gate speed of approximately 60 ns. The development of this system may impact the quantum computing landscape by improving scalability and performance benchmarks.
