Rigetti Computing launches 108-qubit Cepheus-1-108Q quantum computing system

5 articles · Updated · evertiq.com · Apr 24

Cepheus-1-108Q is Rigetti’s largest system, featuring twelve interconnected 9-qubit chiplets and achieving 99.1% median two-qubit gate fidelity.
This modular system triples the qubit count and chiplet number compared to Rigetti’s previous 36-qubit model, marking a significant step in scalable quantum computing.
Rigetti’s proprietary chiplet-based architecture underpins this advance, aiming to enable future fault-tolerant quantum computers and reinforce the company’s leadership in quantum hardware innovation.
