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's stock, listed under the ticker RGTI, surged by 30% on July 16 following the announcement of a breakthrough in quantum computing technology.

The company reported achieving a 99.5% median two-qubit gate fidelity on its modular 36-qubit system, a significant milestone in the quest for commercial viability in the quantum computing sector. For more details, visit the original source. Based in Berkeley, Rigetti's latest achievement marks a twofold reduction in error rates compared to its previous results, bringing the possibility of practical quantum computing applications closer to reality. This development is supported by Rigetti's proprietary modular chip technology, which integrates four 9-qubit "chiplets" to form a 36-qubit system. This innovative approach uses established semiconductor industry techniques to enable scalability while maintaining high performance, addressing a critical challenge in the field where error rates typically increase with system size. CEO Subodh Kulkarni highlighted the advantages of superconducting qubits, noting their gate speeds are over 1,000 times faster than other modalities such as ion trap and pure atoms, and their scalability.

Unlike competitors employing trapped ions or atoms, Rigetti's superconducting qubits function at extremely low temperatures, reducing electrical resistance and allowing them to sustain quantum states for extended periods. The timing is advantageous for investments in quantum technology, as the sector gains momentum with companies transitioning from research to commercial applications. Rigetti plans to launch its 36-qubit system on August 15 and aims to deliver a system with over 100 qubits by the end of 2025. Despite these technical achievements, Rigetti faces challenges in monetizing its advancements. The company has reported year-over-year revenue declines for four consecutive quarters, with Q2 projections indicating adjusted losses of $0.04 per share on $1.87 million in revenue. In Q1 2025, Rigetti reported revenue of $1.5 million, a significant drop from $3.1 million in the same period the previous year.

However, Rigetti has secured strategic wins, including selection for DARPA's quantum benchmarking initiative, advancing to Stage A with a $1 million award. Kulkarni emphasized the program's importance, noting that DARPA selected only 15 companies from over 100 applicants to develop "utility-scale quantum computing" within seven years. Rigetti Computing’s stock has surged 1,300% over the past year, raising its valuation to about $1 billion, a rise fueled by advances in its quantum computing technology. The company recently announced it achieved 99.5% median two-qubit gate fidelity on its 36-qubit modular system, halving previous error rates and marking key progress toward commercial quantum hardware. CEO Subodh Kulkarni projects that true commercial traction and quantum advantage are about four years away. Rigetti's systems are already integrated with major cloud platforms such as Amazon Braket and Microsoft Azure.

The quantum computing sector is expected to reach $100 billion within a decade, positioning Rigetti as a contender alongside industry giants. Rigetti’s focus on improving technical milestones and building institutional trust underscores its ambitions for leadership in the field.
