Key Highlights
- Rigetti Computing introduced its 108-qubit Cepheus-1-108Q system for public use on Amazon Braket and Rigetti’s proprietary cloud infrastructure
- The platform represents the industry’s largest modular multi-chip quantum computer, delivering three times the capacity of Rigetti’s earlier 36-qubit offering
- The company announced intentions to deploy up to $100M in the UK for a quantum system exceeding 1,000 qubits over the next 3–4 years
- Benchmark maintained its Buy recommendation on RGTI; Mizuho continues with an Outperform rating pointing to potential upside exceeding 100%
- RGTI shares advanced from approximately $12.90 on March 30 to $16.79 by April 14
Rigetti Computing (RGTI) experienced a rally exceeding 10% on Tuesday following the company’s announcement that its 108-qubit Cepheus-1-108Q quantum system has entered general availability. Users can now access the platform via Amazon Braket as well as Rigetti’s proprietary cloud infrastructure.
The Cepheus-1-108Q stands as the industry’s largest modular multi-chip quantum computer currently available. The system delivers three times the qubit capacity compared to Rigetti’s prior 36-qubit architecture.
The platform achieves 99.1% median two-qubit gate fidelity. Rigetti has set a goal of reaching 99.5% by late 2026, representing progress in both scale and precision.
Access to the system comes through two channels: Rigetti’s cloud platform or AWS’s Amazon Braket service. This dual-access approach enables corporate clients, government agencies, and research institutions already operating within the AWS infrastructure to utilize the quantum hardware.
RGTI shares advanced from roughly $12.90 on March 30 to $16.79 by April 14. During intraday trading, the stock began at $15.72 before reaching a peak of $16.81.
United Kingdom Investment and University Partnerships
Rigetti revealed plans to commit up to $100M toward UK operations, targeting deployment of a quantum system surpassing 1,000 qubits within a 3–4 year timeframe. This initiative corresponds with a UK government program featuring up to £2 billion allocated for quantum technology development.
Regarding academic collaborations, Rigetti completed a sale of a nine-qubit Novera processing unit to the University of Saskatchewan. This installation establishes Rigetti’s technology as the foundation for the university’s inaugural quantum computing system, enabling research across materials science, algorithm development, and architectural design.
Wall Street Perspectives
Benchmark adjusted its price target on RGTI downward from $35 to $25 while preserving its Buy recommendation. After engaging with company leadership, the firm indicated stronger conviction in Rigetti’s technological capabilities and strategic direction.
Mizuho similarly reduced its target from $43 to $33, acknowledging intensifying competitive dynamics and elevated capital expenditures. The firm retained its Outperform rating, characterizing RGTI as a quantum computing opportunity approaching a pivotal growth phase with potential returns exceeding 100%.
From a financial perspective, Rigetti remains in early-stage development. The company generated approximately $7.1M in annual revenue alongside substantially negative margins and EBITDA of roughly -$15.8M in the most recent quarter. Cash and short-term investments total around $443.5M with negligible debt obligations.
The price-to-sales multiple stands above 700, indicating that share price movement responds primarily to announcements, development timelines, and market sentiment rather than profitability metrics.
Year-to-date through today’s session, RGTI shares remain down 31.69%, providing perspective on the magnitude of the recent rebound from the low-$13 range.
The commercial launch of the Cepheus-1-108Q system with Amazon Braket integration represents the catalyst behind today’s price movement.
