Rigetti Computing, a pioneer in the field of quantum computing based in Berkeley, California, has made headlines with a groundbreaking announcement that could redefine the future of this nascent technology. The company has achieved a remarkable milestone, demonstrating a median two-qubit gate fidelity of 99.5% on its modular 36-qubit system. This achievement not only establishes Rigetti as a leader in quantum computing but also signals a promising shift towards making quantum technology commercially viable. As interest in quantum computing intensifies, particularly amidst a backdrop of significant investments in artificial intelligence, Rigetti’s advancements have caught the attention of investors and industry experts alike, igniting discussions about the practical applications... Gate fidelity is a critical metric in quantum computing, indicative of how accurately a quantum computer can perform operations. A two-qubit gate allows for the interaction between two qubits, which is essential for complex calculations.

The achievement of 99.5% fidelity means that Rigetti’s quantum system can perform operations with a significantly reduced error rate, enhancing its reliability for practical applications. According to Rigetti’s CEO Subodh Kulkarni, the advantages of superconducting qubits, which include gate speeds over 1,000 times faster than traditional methods like ion trap and pure atoms, are central to this success. This leap in fidelity not only improves the performance of quantum systems but also contributes to the scalability needed for larger quantum computers. The reduction in error rates marks a critical step toward overcoming one of the most formidable challenges in quantum computing: maintaining coherence and accuracy in quantum states during calculations. As quantum computers advance, the implications for various industries could be transformative, potentially leading to breakthroughs in fields such as cryptography, materials science, and pharmaceuticals. Following the announcement of its technical achievement, Rigetti’s stock saw a significant uptick, rising more than 30% to approximately $16.57 per share, a six-month high.

While this surge reflects positive investor sentiment, it also highlights the volatility of the quantum computing market. Rigetti’s stock performance, while impressive, remains below the highs reached in the previous year during a broader rally in quantum-related stocks. Rigetti Computing, Inc. (Nasdaq: RGTI) has achieved its mid-year performance milestone of 99.5% median two-qubit gate fidelity on its modular 36-qubit system. This represents a 2x reduction in median two-qubit gate error rate compared to Rigetti’s previous results on its 84-qubit single-chip Ankaa™-3 system. The 36-qubit system is composed of four 9-qubit chiplets tiled together, utilizing Rigetti’s proprietary modular chip technology.

The modular chip technology is intended to support Rigetti’s path to building higher qubit count systems. Rigetti implements CZ gates, which are computationally equivalent to iSWAP gates, for executing quantum circuits. The company aims to leverage techniques from the semiconductor industry to enable the scaling of its superconducting qubit systems. Rigetti operates quantum computers over the cloud and provides on-premises quantum computing systems, designing and manufacturing its chips at Fab-1. The achievement of this gate fidelity milestone on the modular system is positioned as a step towards Rigetti’s goal of developing larger qubit count systems. Rigetti plans to launch its 36-qubit system on August 15, 2025.
