Amazon Braket has integrated Rigetti's Cepheus-1-108Q, marking the first availability of a gate-based quantum processor exceeding 100 qubits on the platform. The device leverages a modular multi-chip architecture combining twelve 9-qubit chiplets and switches to CZ gates, which are better suited for parity-check circuits essential for future error correction. This expansion provides researchers with increased computational complexity and flexible access models for diverse quantum workflows.

Amazon Braket Adds First Gate-Based QPU With 100+ Qubits

Quantum ZeitgeistJune 2, 20266 min read

Amazon Braket now features Rigetti’s Cepheus-1-108Q, a superconducting quantum processor with 108 qubits—the first gate-based device exceeding 100.

Amazon Braket now offers access to Rigetti’s Cepheus-1-108Q, a superconducting quantum processing unit featuring 108 qubits and the first gate-based quantum device with over 100 qubits available on the service. The new processor replaces the Ankaa-3 system and utilizes Rigetti’s multi-chip architecture, tiling twelve 9-qubit chiplets into a single processor. This design builds upon the Cepheus-1-36Q system, tripling both the number of chiplets and the total qubit count. Customers can utilize the device for on-demand access, priority access through Amazon Braket Hybrid Jobs, or dedicated reservations, with the system providing 20 hours of quantum task processing availability every day. Rigetti’s newly launched Cepheus-1-108Q processor boasts 108 qubits, marking the first time a gate-based quantum device exceeding…
