Amazon Braket adds support for Rigetti's 108-qubit Cepheus QPU

Amazon Braket Cepheus-1-108Q Device Launch

Amazon Braket now offers access to Rigetti's Cepheus-1-108Q device, the first 100+ qubit superconducting quantum processing unit (QPU) available on Amazon Braket. This device uses Rigetti's modular multi-chip architecture, featuring a 3x4 array of twelve 9-qubit chiplets with tunable couplers and intermodule couplers between chiplets.

Key improvements include:

• CZ Gates: Introduced to replace iSWAP gates, providing higher resilience to phase errors and reduced leakage errors.
• Use Cases: Enables running deeper circuits for chemical simulation, combinatorial optimization, and machine learning.
• SDK Support: Available for use with the Braket SDK, Qiskit, CUDA-Q, and Pennylane.
• Pulse-level Control: Available for researchers needing low-level hardware access.

What to do

• View the device on the Amazon Braket Management Console
• Read the Amazon Braket documentation
• Apply for AWS credits to support experiments
