RIGETTI Computing (NASDAQ: RGTI) is advancing its position in the quantum computing market through the general availability of its 108-qubit Cepheus-1 system across multiple major cloud platforms.
The Cepheus-1 system is now accessible via Rigetti Quantum Cloud Services, Amazon Braket, Microsoft Azure Quantum and qBraid, expanding its commercial reach significantly.
Management described Cepheus-1 as currently among the most powerful generally available gate-based quantum computers on the market during the company’s first-quarter 2026 earnings call.
The launch also validates Rigetti’s chiplet-based scaling architecture, which management considers a key differentiator as the company targets systems exceeding 1,000 qubits over the next few years.
Prototype systems have already demonstrated 99.9% two-qubit gate fidelity at significantly faster gate speeds, reflecting continued improvements in fidelity metrics across Rigetti’s hardware.
Management expressed confidence in reaching “quantum advantage” within roughly three years, supported by advancements in error mitigation, control systems and scaling technologies.
On the financial side, first-quarter revenues surged nearly 199% year over year to $4.4 million, driven primarily by deliveries of its on-premises Novera quantum processing units and government-related contracts.
Management expects additional Novera revenues to be recognized in the second quarter and remains on track to deliver the $8.4 million C-DAC 108-qubit system in India later this year.
Shares of RGTI have declined 11.1% in the year-to-date period, closely in line with the broader industry’s decline of 11.2%.
From a valuation standpoint, Rigetti Computing trades at a price-to-book ratio of 14.02, above the industry average, and carries a Value Score of F according to Zacks Investment Research.
The Zacks Consensus Estimate for Rigetti Computing’s 2026 earnings implies a significant 70.3% improvement from the year-ago period, though the company currently carries a Zacks Rank of 4, categorized as Sell.
Elsewhere in the quantum space, D-Wave Quantum (NYSE: QBTS) has been broadening its long-term opportunity through its acquisition of Quantum Circuits, strengthening its exposure to gate-model quantum computing alongside its core annealing technology.
D-Wave has also outlined long-term plans targeting scalable logical qubits and improved coherence capabilities, reinforcing its ambition to compete more directly in the broader fault-tolerant quantum computing race.
Arqit Quantum is pursuing a separate path within the quantum ecosystem, focusing on cybersecurity and quantum-safe encryption through its SKA-Platform, which is designed to protect enterprises and governments against future quantum cyber threats.
Arqit has been expanding partnerships with telecom operators, defense organizations and enterprise software providers as global demand for post-quantum security solutions continues to grow.
