Rigetti Computing has launched the 84-qubit Ankaa-3 quantum system, achieving a milestone 99.5% median two-qubit gate fidelity
Ankaa-3 halves error rates compared to previous systems, with 99.5% fidelity for fSim gates and 99.0% for iSWAP gates
The system features a novel cryogenic hardware design that reduces metal content at the coldest point, improving thermal management and cost per qubit
A redesigned qubit chip, developed with Fermilab’s SQMS, increases coherence and qubit lifetimes using advanced metal deposition techniques
The Alternating-Bias Assisted Annealing (ABAA) process for Josephson junctions enables precise qubit frequency targeting and higher gate fidelity
Ankaa-3’s scalable architecture supports 3D signal transmission and modular chip integration for future expansion
The improved fidelity and scalability make Ankaa-3 suitable for complex quantum algorithms and real-world applications in AI, finance, climate, and medicine
The system is energy-efficient and cost-effective due to its advanced cooling and hardware design
Ankaa-3 is accessible globally via Rigetti Quantum Cloud Services, and will soon be available on Microsoft Azure and Amazon Braket
The modular, cloud-accessible design allows researchers and businesses worldwide to use Ankaa-3 without owning quantum hardware
