Insights
The release of Rigetti's 84-qubit Ankaa™-2 system represents a significant advancement in the field of quantum computing. The system's 98% median 2-qubit fidelity is a critical metric, as it indicates the accuracy with which the system can perform quantum logic operations, which are the building blocks of quantum algorithms. High fidelity is essential for practical quantum computing applications, as it reduces the need for error correction and increases the potential for quantum advantage — the point at which quantum computers can solve problems faster or more efficiently than classical computers.
The Ankaa-2's fourth generation chip architecture with tunable couplers and a square lattice is an innovative approach that allows for more precise control over qubit interactions. This is an important factor in scaling up quantum systems since managing qubit coherence and interaction is one of the main challenges in developing larger and more reliable quantum processors. The system's ability to tile multiple chips together is indicative of a modular approach that could be key in achieving the necessary qubit counts to tackle complex computational tasks.
From a financial perspective, the public availability of the Ankaa-2 system via Rigetti's Quantum Cloud Services (QCS™) could potentially open new revenue streams for the company. By offering access to a more powerful and reliable quantum processing unit (QPU), Rigetti may attract a broader customer base, including enterprises and research institutions that require high-performance computing capabilities. The improvement in performance and fidelity compared to previous systems suggests that the company is successfully iterating on its technology, which might lead to increased investor confidence and potentially positive impacts on Rigetti's stock valuation.
However, it is important to consider the capital-intensive nature of quantum computing R&D and the long-term investment horizon required before substantial returns can be realized. Investors should evaluate the company's burn rate, funding status and competitive position in the market to understand the potential risks and rewards associated with such an investment.
The quantum computing market is rapidly evolving and the launch of the Ankaa-2 system by Rigetti positions the company as a key player in this space. With a high-performance QPU now publicly available, Rigetti competes with other quantum computing firms that are also racing to increase qubit counts and fidelities. The market demand for quantum computing is expected to grow as more industries recognize the potential applications, ranging from materials science to financial modeling.
It is crucial to monitor how Rigetti's technology is adopted and integrated into various sectors. The company's progress on its QPU roadmap and qubit performance will be closely watched by competitors and potential clients. If Rigetti can maintain its technological lead and continue to deliver on its promises, it may secure a significant share of the market. Nevertheless, the commercial viability of quantum computing as a whole remains uncertain and the ability to convert technological advancements into profitable solutions will be the ultimate test for Rigetti and its peers.

BERKELEY, Calif., Jan. 04, 2024 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, announced today that its 84-qubit Ankaa™-2 quantum system was made publicly available to all of its customers via Rigetti’s Quantum Cloud Services (QCS™) on December 20, 2023. The Ankaa-2 system is based on Rigetti’s fourth generation chip architecture that features tunable couplers and a square lattice, enabling high fidelity 2-qubit operations compared to the Company’s previous systems. Ankaa-2 is also the Company’s highest qubit count quantum processing unit (QPU) available to the public.
Following the internal deployment of Ankaa-1, the Company made iterative improvements through internal R&D to support enhancements to Ankaa-2. As a result, Ankaa-2 achieved a
- Implementation of a new chip fabrication process, leading to qubits with fewer atomic defects that would otherwise reduce quantum coherence times
- Incorporation of new superconducting PCB technology that improves thermal performance
- Electronics improvements that generate control signals with less noise
“Rigetti’s focus on improving our median 2-qubit fidelities is a crucial part of our mission to build the world’s most powerful computers. Useful quantum computers will need not only a large number of qubits, but also high quality qubits. Reaching
“I am thrilled with the progress we are making with our Ankaa-class architecture against our QPU roadmap and qubit performance. To reach quantum advantage we know we need high performance qubits, and a lot of them. We’ve already designed and deployed a modular architecture, tiling multiple chips together demonstrating what we believe is the way forward towards building larger systems. We believe a densely connected square lattice with tunable couplers that allows us to control qubit interactions is the foundation for driving qubit performance. A 2.5x increase in error performance against our previous QPUs, increasing our fidelities by
The public launch of the Ankaa-2 system follows the release of the Novera™ QPU, Rigett’s first commercially available QPU, which is based on the same Ankaa-class architecture and designed for hands-on access to state-of-the-art quantum hardware for foundational quantum computing R&D.
