Rigetti Computing

A full-stack quantum computing company specializing in superconducting quantum processors and hybrid quantum-classical systems.

Rigetti Computing - About

Rigetti Computing is a publicly traded integrated systems company headquartered in Berkeley, California. Founded in 2013, the company designs and manufactures superconducting quantum processors (QPUs) at its own fabrication facility in Fremont, California, and develops the full quantum stack, including cryogenic systems and the Quantum Cloud Services (QCS) platform.

The company's hardware portfolio includes the 84-qubit Ankaa-3, the chiplet-based Cepheus-1-36Q, and the Novera, a commercially sold 9-qubit merchant QPU. Rigetti provides access to its infrastructure through its own data centers and cloud partners such as Microsoft Azure and Amazon Braket.

Positioned as a pure-play quantum computing firm, Rigetti differentiates itself through its in-house fabrication capabilities and a chiplet architecture designed for scaling. Innovation in this space is critical for the company as it moves from an early commercial stage toward larger-scale quantum systems.

Ideas that could help Rigetti Computing

Topological State-Death Predictor
A diagnostic capability for quantum systems that predicts 'entanglement sudden death' based on the integer linking properties of soliton configurations.
Why it helps: Helps in understanding the decoherence of qubits by mapping it to the topological reconnection of Hopf fibers.
