id=\"Introduction\"><\/span>Introduction<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.rigetti.com\/\" target=\"_blank\" rel=\"noopener\">Rigetti Computing (ticker: RGTI)<\/a> is a superconducting quantum computer manufacturer located in Berkeley, California. The company also has a Forest cloud platform that allows programmers to access its quantum computers to write quantum algorithms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Founding_of_the_company\"><\/span>Founding of the company<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti was founded in 2013 by Chad Rigetti, a physicist with an IBM quantum computer background. The company emerged from the startup incubator Y Combinator in 2014. In February 2016, Rigetti created its first quantum processor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Business\"><\/span>Business<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti Computing is headquartered in Berkeley, California, and its main operating projects are the development of systems and cooling equipment.<\/p>\n\n\n\n<p>The company also operates its Fab-1 manufacturing plant in nearby Fremont. Fab-1&#8217;s rapid prototyping laboratory is designed to quickly create integrated circuits. Laboratory engineers are responsible for designing and producing 3D integrated quantum circuit products based on quantum hardware of qubits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Initial_Public_Offering\"><\/span>Initial Public Offering<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti Computing went public on March 2, 2022 through a special purpose acquisition company (SPAC) merger with Supernova Partners Acquisition Company II (ticker: SNII). The ticker after the merger is RGTI.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Technology\"><\/span>Technology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Core_Technology\"><\/span>Core Technology<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti uses superconductor technology, which cannot operate at normal room temperature. The method used by Rigetti is the same as the quantum technology used by IBM and Alphabet, so Rigetti is forced to compete directly with these two companies.<\/p>\n\n\n\n<p><strong>Note<\/strong>: For information about superconductor technology, please click my previous post of &#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2023\/08\/03\/superconductor-progress\/\">Why are superconductors important? current progress and related companies<\/a>&#8220;<\/p>\n\n\n\n<p>Rigetti focuses on gate-based quantum systems, emphasizing modular superconducting qubit architectures for universal quantum computing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Rigettis_latest_technological_development\"><\/span>Rigetti&#8217;s latest technological development<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti&#8217;s latest technological development product is the Ankaa-3 system that can run 84 qubits, with a dual qubit fidelity of up to 99.5%. Its modular architecture enables future chip interconnectivity, while its AI-assisted calibration and proprietary ABAA manufacturing process are designed to reduce errors and expand the number of qubits. Rigetti plans to launch a 108-qubit system by the end of 2025, and is focused on long-term applications in machine learning, optimization, and materials science.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Technology_Milestones\"><\/span>Technology Milestones<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The 84-qubit Ankaa-3 system, launched in December 2024, achieved a median iSWAP of 99.0% and fSim gate fidelity of 99.5%\u2014halving the error rate compared to previous generations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Products_and_Business\"><\/span>Products and Business<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Products\"><\/span>Products<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In December 2024, Rigetti launched the Novera QPU, a 9-qubit commercial version of its own quantum computer, priced at $900,000. Several major government and research customers have already ordered these QPUs. The company also recently deployed its first 84-qubit Ankaa-3 system, designed to detect more than 99% of processing errors, and plans to deploy a more powerful 100-qubit system this year with an even higher error detection rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Everything_in-house\"><\/span>Everything in-house<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Several of Rigetti\u2019s main competitors rely on partners for various components, but Rigetti controls everything from chip manufacturing to cloud access; everything in-house.<\/p>\n\n\n\n<p>Rigetti designs and manufactures its own quantum processors (QPUs) and allows developers to write their own quantum algorithms on its Forest cloud platform. This one-stop-shop model makes it a \u201cfull-end\u201d quantum computing company.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Customers_and_partners\"><\/span>Customers and partners<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Dependence_on_government_orders\"><\/span>Dependence on government orders<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rigetti\u2019s growth model is overly dependent on government deals, and Rigetti continues to rely heavily on U.S. government contracts to fund and validate its quantum technology. For example, the company renewed a $1.5 million contract with the U.S. Air Force Research Laboratory (AFRL) for quantum software development, and a $3.9 million contract with the U.S. Defense Advanced Research Projects Agency (DARPA) to advance the scalability of quantum hardware. Rigetti also signed a multi-year project with the U.S. Department of Energy (DoE) Center for Superconducting Quantum Materials and Systems, and delivered its 84-qubit Ankaa-1 system to the DoE\u2019s Quantum Systems Accelerator.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pros_and_cons_of_this_model\"><\/span>Pros and cons of this model<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>These collaborations provide valuable non-dilutive capital and technology returns, solidifying Rigetti\u2019s position as a trusted partner in early-stage quantum R&amp;D for the government. However, this predominantly public sector revenue stream raises questions about its scalability and commercial maturity. Government projects typically have long procurement cycles and may not develop into high-margin term contracts. To date, there is little evidence of Rigetti\u2019s substantive adoption by the private sector, suggesting that its reliance on public funding suggests that its business model is still in the validation phase. While these partnerships are strategic, the lack of diversified revenue streams limits visibility into Rigetti&#8217;s long-term business trajectory.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span
