Rigetti Computing (NASDAQ: RGTI) has restructured its executive leadership and operational framework to separate system delivery from core technology development. The company appointed David Rivas as Chief Operating Officer and Andrew Bestwick, Ph.D., as Chief Technology Officer, effective August 18, 2026. This organizational shift is designed to scale the deployment of on-premises quantum systems while allowing engineering teams to concentrate on advancing processor performance.
The new structure establishes a dedicated Systems Delivery organization led by Rivas. In this role, he will oversee fabrication operations, systems delivery, software engineering, applications, business development, government programs, supply chain, and facilities. Previously serving as Chief Technology Officer since February 2023, Rivas joins Rigetti in March 2019 as Senior Vice President of Systems and Services.
Andrew Bestwick, Ph.D., currently Senior Vice President, Quantum Systems, has been appointed Chief Technology Officer. Dr. Bestwick will oversee quantum processor development, chip fabrication development, and hardware engineering. He leads the architecture of Rigetti’s Cepheus-class multi-chip systems. The technology organization remains Rigetti’s largest engineering group, underscoring the company’s focus on its published technology roadmap.
Operational Context
Rigetti cites increased demand for customer deployments of on-premises systems as the driver for this structural change. The company sells systems ranging from 9-qubit Novera units to large-scale 108-qubit Cepheus-class systems. Historically, installation and customer support activities were supported within the engineering organization. The new model creates dedicated leadership for system deployment and customer success.
| Executive | New Role | Key Responsibilities |
|---|---|---|
| David Rivas | Chief Operating Officer | Fabrication, systems delivery, software engineering, business development, supply chain |
| Andrew Bestwick, Ph.D. | Chief Technology Officer | Quantum processor development, chip fabrication, hardware engineering |
Both executives report to President and Chief Executive Officer Dr. Subodh Kulkarni. Dr. Kulkarni stated that the structure gives commercial and operational teams clear accountability for scaling system delivery while giving the technology organization greater focus on innovation.
What the Numbers Show
The restructuring highlights a strategic divergence between hardware scaling and technical fidelity targets. Rigetti is deploying larger multi-chip systems, specifically the Cepheus-1-108Q based on twelve 9-qubit chiplets tiled together. Simultaneously, the company maintains a specific performance target of 99.5% median two-qubit gate fidelity on this system. By separating operational execution from technical research, Rigetti aims to manage the complexity of delivering these large-scale systems while pursuing high-fidelity metrics.
Rigetti’s quantum computers are based on superconducting qubits, achieving gate speeds of 50-70 nanoseconds. The company designs and manufactures its chips in-house at Fab-1, its dedicated quantum device manufacturing facility. It also operates quantum computers over the cloud through its Rigetti Quantum Cloud Services platform.
How might the separation of system delivery from core R&D impact Rigetti's short-term revenue recognition timelines for its on-premises Cepheus-class systems?
Given the 99.5% fidelity target, what are the primary technical hurdles Andrew Bestwick's team faces in scaling multi-chiplet architectures without compromising gate performance?
Will the new operational structure allow Rigetti to reduce the lead time for customer installations, thereby improving competitiveness against cloud-only quantum providers?
