The Technology Behind Rigetti Computing
Superconducting Qubits
Rigetti Computing uses superconducting qubits, known for their fast gate speeds, high coherence times, and relative ease of integration with current semiconductor infrastructure. These qubits rely on Josephson junctions that exhibit quantum behavior at cryogenic temperatures.
Rigetti manufactures these qubits at Fab-1, its proprietary fabrication facility, ensuring tight control over design iterations and quality.
This internal manufacturing capability allows Rigetti to innovate quickly, test new quantum architectures, and iterate faster than companies that rely on third-party fabrication.
Modular Architecture
Rigetti’s Novera 9-qubit chip exemplifies its modular design philosophy. Unlike monolithic designs, modular architectures make it easier to scale quantum systems by linking together smaller units. This design also improves fault tolerance and system maintainability.
The company plans to tile Novera chips to form larger quantum processors, enabling flexible deployment depending on performance needs. This modularity aligns with trends in classical high-performance computing, offering familiarity for IT teams while still pushing quantum boundaries.
Gate Fidelity Targets
Rigetti is aiming to achieve 99.5% two-qubit gate fidelity, a threshold believed to be critical for enabling near-term quantum advantage. Improving gate fidelity reduces the error rate in quantum circuits, making computations more reliable and expanding the set of problems quantum systems can solve.
Achieving this level of fidelity positions Rigetti as a viable player in high-stakes quantum research domains like pharmaceuticals, materials science, and complex financial modeling.
Quantum Cloud Services (QCS)
Hybrid Quantum-Classical Environment
Rigetti’s Quantum Cloud Services (QCS) platform connects quantum computers directly with classical computing environments, enabling hybrid algorithms like the Variational Quantum Eigensolver (VQE) and Quantum Approximate Optimization Algorithm (QAOA).
Users can deploy and run workloads from within familiar environments, such as Jupyter notebooks and Python SDKs, which makes experimentation accessible to a wider developer base. The cloud-native approach also allows Rigetti to iterate on firmware and software improvements without user-side changes.
For developers with an account on platforms like eToro who are closely tracking quantum investments, QCS provides a compelling intersection of technology and finance.
Developer Tools: Forest and Quil
Forest, Rigetti’s open-source developer suite, includes the Quil programming language, a compiler, and simulator tools. Quil provides fine-grained control over qubit manipulation, essential for researchers exploring novel quantum algorithms.
Rigetti’s investment in open standards encourages a robust developer community, which in turn leads to faster discovery of practical quantum use cases in physics. By supporting integrations with classical tools and libraries, Forest makes it easier for traditional developers to onboard into the quantum world.
Strategic Collaborations and Global Expansion
Partnership with Quanta Computer
In 2025, Rigetti entered a strategic partnership with Quanta Computer, one of the world’s largest electronics manufacturers. The $200 million commitment from each company aims to scale production of quantum processors and establish co-located quantum-classical data centers.
This partnership enables Rigetti Computing Inc to take advantage of Quanta’s global logistics and manufacturing scale, reducing time-to-market for new hardware and expanding accessibility to quantum computing.
Participation in DARPA
Rigetti’s inclusion in DARPA’s Quantum Benchmarking Program underscores its credibility and technical expertise. The program focuses on evaluating the real-world performance of quantum systems and establishing standardized benchmarks for future adoption.
Participation also provides Rigetti access to government resources and research insights, helping it stay at the forefront of national quantum initiatives.
Global Deployments
Beyond the U.S., Rigetti has made notable international inroads. The deployment of its Novera-based quantum computer at Horizon Quantum Computing’s Singapore headquarters showcases the company’s readiness for international market adoption.
Such deployments offer local researchers direct access to Rigetti’s quantum capabilities, catalyzing the development of region-specific use cases in logistics, finance, and urban planning.
Financial Landscape
Revenue Trends
While Rigetti reported a drop in revenue year-over-year ($2.27M in Q1 2025 vs. $3.38M in Q1 2024), this aligns with its high R&D investment cycle. The company is prioritizing long-term breakthroughs over short-term profit, a common trend among deep tech firms in pre-commercial stages.
Retail investors tracking the ticker RGTI on eToro and similar platforms are closely watching these developments as the company moves toward product maturity and revenue scaling.
Market Sentiment
Despite lower earnings, investor sentiment remains optimistic. The 9% stock uptick following Q1 results was fueled by confidence in the company’s roadmap and recent DARPA involvement. Analysts cite Rigetti’s technical milestones and partnerships as strong signals of future growth.
Public market interest in quantum stocks continues to rise, and Rigetti’s dual focus on hardware and services makes it appealing for a diversified quantum investment thesis.
