Quantum Computing Stocks: Rigetti Sets Record, D-Wave Quantum Rises Amid Jim Cramer's Endorsement

Rigetti Computing reached a 99.5% median fidelity rate for two-qubit gates on its 36-qubit modular system, leading to a 40% stock gain. D-Wave Quantum shares rose nearly 30% on retail interest and possibly a recommendation from CNBC's Jim Cramer. Quantum Computing announced its first commercial sale of quantum security technologies, while IonQ completed the acquisition of Capella Space to develop a space-based QKD network.

Rigetti Computing achieved a significant milestone in quantum computing technology, reaching a 99.5% median fidelity rate for two-qubit gates on its 36-qubit modular system. This represents a substantial improvement over the company's previous best results on its 84-qubit single chip system, with a twofold reduction in median two-qubit gate error rate [1]. The achievement highlights Rigetti's progress in developing scalable quantum computing systems using its proprietary modular chip technology.

Following this announcement, Rigetti's stock experienced a notable 40% gain, reflecting investor optimism about the company's advancements and potential for future growth [2]. The company's success in reaching this milestone is expected to accelerate its path towards commercializing quantum computing solutions.

In parallel developments, D-Wave Quantum has seen a surge in retail interest, with its stock rising nearly 30% on July 21, 2025 [3]. The increase is attributed to a new study revealing that more than half of global business leaders plan to adopt quantum computing within two years. The survey, conducted in partnership with Wakefield Research, underscores the growing demand for quantum computing technologies to solve complex business problems.

Additionally, Quantum Computing announced its first commercial sale of quantum security technologies, while IonQ completed the acquisition of Capella Space to develop a space-based Quantum Key Distribution (QKD) network. These moves indicate the industry's continued push towards practical applications of quantum computing, with a focus on security and innovation.

As the quantum computing sector continues to evolve, these developments highlight the increasing interest and investment in the technology. Companies like Rigetti and D-Wave are at the forefront of innovation, driving the industry towards new commercial and technological frontiers.
