Amazon Braket integrated access to Rigetti’s first 100+ qubit quantum processing unit, the Cepheus-1-108Q, featuring a 3x4 array of twelve 9-qubit chiplets interconnected via tunable couplers. It replaces earlier iSWAP gates with CZ gates that are more resilient to superconducting phase errors, enabling deeper quantum circuits.
This device supports quantum applications like chemical simulations, optimization, and machine learning and allows users both software-level Braket SDK programming and pulse-level hardware control. Availability is currently limited to the US West (N. California) Region, with resources provided for onboarding researchers and developers.
