Rigetti Announces Launch Of Ankaa 3 Quantum Computer
Rigetti Computing Launches 84-Qubit Ankaa 3 System with 99.5% Median Two-Qubit Gate Fidelity. Rigetti tops the market with its revolutionary hardware revamp that boosts performance, scalability, and authenticity.
Features
Better Qubit Integrity
The median two-qubit gate integrity of 99.5% in Ankaa 3 cuts error rates in half compared to previous systems. Its median fidelity for fSim gates is 99.5% and for iSWAP gates is 99.0%, which is crucial for complex quantum algorithms like random circuit sampling.
Innovational Cryogenic Architecture
A novel cryogenic hardware design reduces metal content at the refrigerator's coldest point. This innovation improves heat management, magnetic/environmental shielding, qubit cost, and system performance.
Improved Qubit Chip
Rigetti redesigned its qubit for coherence. In collaboration with Fermilab-led SQMS, a new metal deposition approach for qubit circuitry resulted in increased T₁ baseline and longer qubit lifetimes. The circuit configuration was designed to reduce qubit losses.
Josephson Junctions ABAA Method
Rigetti's Alternating-Bias Assisted Annealing (ABAA) technique creates Josephson junctions in the Ankaa 3 chip. This method increases two-qubit gate performance and yield by accurately targeting qubit frequency, increasing fidelity.
Scalable architecture
Ankaa-3 retains Rigetti's scalable chip design with 3D signal transmission. This design supports the integration of many qubit devices, making larger quantum systems easier to create. Rigetti plans to release a system with more than 100 qubits by the end of 2025 and a 36-qubit system constructed on four 9-qubit chips tiled together by the middle of 2025 to reduce mistake rates by twofold.
