Rigetti Computing builds on Transmon qubits, the same family as IBM Quantum and Google Quantum AI. It fabricates its chips at its own facility, Fab-1, rather than through an external foundry, giving it direct control over the fabrication process. It also builds multi-chip systems that link separate processors together, scaling qubit count by combining smaller chips instead of betting on ever-larger single dies.

Rigetti was an early mover in cloud-accessible quantum hardware, through its Quantum Cloud Services platform and Forest/pyQuil software stack. It went public on a US stock exchange in 2022.
