Rigetti Computing Unveils 84-Qubit Ankaa-3 with High Fidelity
Rigetti Computing Introduces the 84-Qubit Ankaa-3 System
Rigetti Computing is thrilled to unveil its latest innovation, the 84-qubit Ankaa-3 system, a remarkable step forward in the realm of quantum computing. With significant enhancements in its architecture, this new quantum computer showcases superior performance and is set to transform the landscape of quantum-classical computing.
Key Features of the Ankaa-3 System
The Ankaa-3 features a comprehensive redesign that improves upon previous models. At its core lies a new cryogenic hardware setup designed to enhance efficiency. This innovation reduces the quantity of metal at the refrigerator’s coldest stage, resulting in improved thermalization, which ultimately leads to better performance while also bringing down costs for each qubit.
Hardware Enhancements
Rigetti has raised the bar by optimizing the qubit chip construction through collaboration with leading research entities, resulting in enhanced coherence and a higher T1 baseline. This optimization is crucial, as it denotes the qubit's lifespan or how long it can maintain its operational state without error.
Advanced Qubit Control Technologies
The Ankaa-3 also integrates Josephson junctions fabricated with a novel technique called Alternating-Bias Assisted Annealing (ABAA). This method allows for precise targeting of qubit frequencies, essential for executing two-qubit gates effectively and improving yields, thus contributing to the overall fidelity of the system.
Significant Achievements in Fidelity
Rigetti is celebrating notable milestones with the Ankaa-3, having achieved a median gate fidelity of 99.5% for fSim gates and 99.0% for iSWAP gates. These figures highlight the company's commitment to reducing error rates, thereby enhancing the reliability of quantum computations.
Future Availability on Cloud Platforms
The Ankaa-3 system will be accessible to partners through the Rigetti Quantum Cloud Services platform, with plans to expand access to major cloud providers, Amazon Braket and Microsoft Azure, in the near future. Users will benefit from operating higher fidelity universal gates across various algorithmic research areas, enhancing capabilities in quantum computing.
Leadership's Vision
Dr. Subodh Kulkarni, CEO of Rigetti, shared the company’s optimism regarding their financial position, noting, "With approximately $225 million in cash reserves and no debt, we are well-positioned to realize our roadmap and performance targets." He affirmed Rigetti's continued leadership in superconducting quantum computing, citing its advantages like rapid gate speeds and established manufacturing processes.
Looking Ahead: The Next Generation of Quantum Systems
As Rigetti sets its sights on the future, the upcoming modular system architecture is scheduled for further enhancements. Planned releases include a 36-qubit system by mid-2025 and future developments that target over 100 qubits.
