The Companys 84-qubit Ankaa-2 system is now publicly available to all of its customers via Rigetti Quantum Cloud Services (QCS). The Ankaa-2 system has achieved a 98% median 2-qubit fidelity, a 2.5x performance improvement compared to the Companys previous QPUs.

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 Rigettis Quantum Cloud Services (QCS) on December 20, 2023. The Ankaa-2 system is based on Rigettis fourth generation chip architecture that features tunable couplers and a square lattice, enabling high fidelity 2-qubit operations compared to the Companys previous systems. Ankaa-2 is also the Companys 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 2% median 2-qubit gate error rate less than half the error rate of the Companys previous systems. These fidelity improvements can be attributed to a variety of technology updates to the Ankaa-2 system:

Rigettis focus on improving our median 2-qubit fidelities is a crucial part of our mission to build the worlds most powerful computers. Useful quantum computers will need not only a large number of qubits, but also high quality qubits. Reaching 98% fidelity on the Ankaa-2 system is the result of years of innovation and commitment from our teams across the technology stack. Now that the Ankaa-2 system is available to all of our customers and partners, I look forward to focusing on continued progress in accelerating this transformational technology, says Dr. Subodh Kulkarni, Rigetti CEO.

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. Weve 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 3%, coupled with our scaling approach, shows us that we have a promising strategy for building increasingly higher performing QPUs to help our customers solve their most pressing problems, says David Rivas, Rigetti CTO.

The public launch of the Ankaa-2 system follows the release of the Novera QPU, Rigetts 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.
