Amazon Braket Adds Rigetti Cepheus-1-108Q QPU (100+ Qubits)
🔬 Amazon Braket now offers access to Rigetti's Cepheus-1-108Q, the first 100+ qubit superconducting QPU available on the service. The device uses a modular 3×4 array of twelve 9‑qubit chiplets with tunable and intermodule couplers and introduces CZ gates with an adiabatic implementation to reduce phase and leakage errors. Customers can run deeper circuits for chemical simulation, combinatorial optimization, and machine learning via the Braket SDK or frameworks such as Qiskit, CUDA‑Q, and Pennylane, and researchers can use pulse‑level control. Cepheus-1-108Q is available in the US West (N. California) Region.
