(Nasdaq: RGTI) (\u201cRigetti\u201d or the \u201cCompany\u201d), a pioneer in full-stack quantum-classical computing, announced today the public launch of its 84-qubit Ankaa-3 system. Ankaa-3 is Rigetti\u2019s newest flagship quantum computer featuring an extensive hardware redesign that enables superior performance. Rigetti also celebrates major two-qubit gate fidelity milestones with Ankaa-3: successfully halving error rates in 2024 to achieve a median 99.0% iSWAP gate fidelity, as well as demonstrating 99.5% median fidelity fSim gates.<\/p>\n<p>Ankaa-3 is now available to its partners via the Rigetti Quantum Cloud Services platform (QCS<sup>\u00ae<\/sup>) and will be coming to Amazon Braket and Microsoft Azure in the first quarter of 2025. Users will be able to operate these higher fidelity and universal iSWAP gates for a wide range of algorithmic research, with a median gate time of 72 nanoseconds. The faster (median 56 nanoseconds), more specialized fSim gates are useful for specific algorithms such as random circuit sampling, as recently demonstrated on Google\u2019s Willow system.<\/p>\n<p>The Ankaa-3 system continues to feature Rigetti\u2019s scalable, industry-leading chip architecture with 3D signal delivery while incorporating major enhancements to key technologies. Leveraging the Company\u2019s full-stack expertise and in-house quantum foundry capabilities, Ankaa-3 demonstrates Rigetti\u2019s ability to deliver increasingly higher performance quantum computers.<\/p>\n<p>The Company\u2019s focus on improving qubit fidelity has resulted in enhancements across the technology stack:<\/p>\n<ul type=\"disc\">\n<li>\n          <strong>All new cryogenic hardware design &#8211; <\/strong>Reducing the amount of metal at the refrigerator\u2019s coldest stage increases efficiency and reduces the cost per qubit. Superior thermalization and magnetic\/environmental shielding also improves system performance. This new design enables scaling up to thousands of qubits. <\/p>\n<\/li>\n<li>\n          <strong>Improved qubit chip &#8211; <\/strong>Rigetti overhauled its qubit chip, leading to improved coherence. Through its collaboration with the Superconducting Quantum Materials &amp; Systems Center (SQMS) led by Fermilab, Rigetti implemented a metal deposition method for qubit circuitry with a higher T<sub>1<\/sub> baseline &#8212; which indicates the lifetime of a qubit. Additionally, the circuit layout was optimized to minimize qubit losses and take advantage of the new higher-coherence process.<\/p>\n<\/li>\n<li>\n          <strong>Josephson junction fabrication with Alternating-Bias Assisted Annealing (ABAA) &#8211; <\/strong>The Ankaa-3 chip features the hallmarks of Rigetti\u2019s Ankaa-class chip architecture with a square lattice of qubits and tunable couplers. The 84-qubit chip\u2019s Josephson junctions are manufactured using Rigetti\u2019s novel ABAA technique. ABAA allows for precise qubit frequency targeting, which enables better execution of two-qubit gates and increases in yield, both of which contribute to higher fidelity. <\/p>\n<\/li>\n<li>\n          <strong>Precise control and flexible gate architecture &#8211; <\/strong>Rigetti has invested heavily in the control technologies underpinning its QPUs. Chip-wide optimization of qubit and tunable coupler frequencies produces fewer unwanted qubit-qubit interactions, and real-time, in-hardware pulse pre-compensation produces gates with lower incoherent errors. Rigetti has also developed a robust calibration process for highly expressive square-root-iSWAP-like gates while solving some of the compilation challenges associated with their practical usage, resulting in an nQA-oriented gate set with significantly lower error rates.<\/li>\n<\/ul>\n<p>\u201cWith approximately $225 million of cash, cash equivalents and available for sale investments and no debt, we are extremely confident in our ability to deliver on our roadmap and performance goals. The remarkable performance of Ankaa-3 reinforces our leadership in the superconducting quantum computing field &#8212; which we believe is the winning modality for high-performance quantum computers due to their many advantages, including fast gate speeds and well-established manufacturing processes,&#8221; says Dr. Subodh Kulkarni, Rigetti CEO.<\/p>\n<p>\u201cOur teams, across the technology stack, work incredibly hard to introduce new, innovative ways to increase our system\u2019s performance. As we continue the journey towards fault tolerance, we are constructing computing systems with capabilities that have not been seen before,\u201d says David Rivas, Rigetti CTO. \u201cAt Rigetti, working closely with our partners, we are committed to finding ways to put those systems to practical use.\u201d<\/p>\n<p>Rigetti plans to introduce the next generation of its modular system architecture, while continuing to increase fidelities, in 2025. By mid-year 2025, the Company expects to release a 36-qubit system based on four 9-qubit chips tiled together, with a targeted 2x reduction in error rates from the current level. By the end of 2025, the Company expects to release a system with over 100 qubits with a targeted 2x reduction in error rates from the current level.<\/p>\n<p>\n        <strong>About Rigetti<\/strong><br \/>\n        <br \/>Rigetti is a pioneer in full-stack quantum computing.
