Rigetti Advances Toward Quantum Advantage With Cepheus Push

Read MoreHide Full Article

Key Takeaways

  • RGTI made its 108-qubit Cepheus-1-108Q system broadly available across major quantum platforms.
  • RGTI's Q1 revenue nearly tripled to $4.4 million, driven by Novera QPU deliveries and contracts.
  • Rigetti targets quantum advantage with a ~1,000-qubit system, 99.9% gate fidelity and error mitigation.

Rigetti Computing (RGTI - Free Report) is strengthening its position in the quantum computing race through a combination of technological advancements and expanding customer adoption. During the first quarter of 2026, the company made its 108-qubit Cepheus-1-108Q system generally available through Rigetti Quantum Cloud Services, Amazon Braket, Microsoft Azure Quantum and qBraid. Management believes the platform is among the world’s most powerful gate-based quantum computers and the largest modular quantum computing system currently on the market.

Built using 12 interconnected 9-qubit chiplets, the system validates Rigetti’s chiplet-based scaling architecture, a key element of its long-term roadmap toward larger and more capable quantum systems. The company also highlighted continued progress in improving gate fidelity and performance, with management targeting approximately 99.5% median two-qubit gate fidelity later in 2026 while maintaining its speed advantages.

Beyond technology milestones, Rigetti continues to gain customer traction across both cloud and on-premises deployments. First-quarter revenues nearly tripled year over year to $4.4 million, primarily driven by deliveries of Novera quantum processing units (QPUs) and related contracts. The company continues to expand its installed base through sales to universities, research institutions and national laboratories. It is also reporting growing interest from commercial customers in industries such as materials science, logistics and financial services.

Importantly, management reiterated its belief that Rigetti can achieve quantum advantage within roughly three years, targeting a system with around 1,000 qubits, 99.9% two-qubit gate fidelity and integrated error mitigation capabilities. Backed by approximately $569 million in cash and no debt, Rigetti is well positioned to continue investing aggressively in scaling its technology platform and capitalizing on emerging opportunities in the rapidly evolving quantum computing market.

Peers Updates

IonQ (IONQ - Free Report) recently opened a new 22,000-square-foot quantum computing R&D laboratory and semiconductor chip testing facility in Boulder, CO, to support the development of future generations of its trapped-ion quantum computing systems. The facility will enable the company to design, test and refine advanced semiconductor ion-trap chips, with plans to install its first quantum computer later this year. By expanding its presence in Colorado's growing quantum technology ecosystem and leveraging the region's deep-tech talent pool, IONQ aims to accelerate innovation, scale production capabilities and advance its roadmap toward fault-tolerant quantum computing.

D-Wave Quantum (QBTS - Free Report) recently announced that it has entered into a non-binding Letter of Intent with the U.S. Department of Commerce for proposed funding of up to $100 million under the CHIPS and Science Act. The initiative aims to support the advancement and large-scale deployment of the company’s annealing and gate-model quantum computing technologies. As part of the proposed arrangement, the U.S. government would receive a $100 million equity stake in D-Wave.

The funding is expected to help expand quantum system development at D-Wave’s planned facility in Boca Raton, FL, as well as its existing research and development operations. The investment could accelerate the commercialization of next-generation quantum platforms, including a 100,000-qubit annealing system and a 10,000-qubit gate-model computer. It could also enhance D-Wave’s competitive standing in the rapidly evolving quantum computing market and support U.S. leadership in critical advanced technologies.
