Rigetti partnering with Quanta on custom control system hardware; $40M investment driving co-development roadmap
Subodh Kulkarni· Rigetti Computing· Quantum· 2026-05-11· about Quanta Services (or similar entity named Quanta)
“Quanta has strong capabilities in server and control electronics, and they have a dedicated team working on control systems that interface with our devices. Going forward, we expect to use Quanta-made control systems as part of our stack... A key accomplishment has been their design of a new control system that we have started including in recent offerings... Over the next year or two, we expect them to continue improving control systems to meet our requirements and to contribute to other parts of the hardware stack.”
Why it matters
Rigetti disclosed a $40M strategic investment from Quanta and is now integrating Quanta-designed control systems into production quantum computers. This is a specific supplier-customer relationship with capex implications and multi-year co-development commitment for a critical hardware subsystem.
Investment implication
Quanta's control electronics expertise is becoming embedded in quantum computing hardware stacks. If Quanta is a public or investable entity, this represents a strategic revenue stream and competitive moat in quantum control electronics. If private, this signals the quantum supply chain is consolidating around specialized hardware vendors.
