Rigetti Quantum Computing

Rigetti Quantum Computing, a quantum computing company, was founded in 2013 by Chad Rigetti and based in Berkeley and Fremont, California. As of 2019, the company has raised over $119 million from investors, including Andreessen Horowitz and Vy Capital and has over 50 U.S. patent applications on file. Rigetti also participated in the YC S14 cohort of Y Combinator and raised an estimated $69,450,000.

Integrated quantum-classical computing leverages today’s existing high-power processors and the advanced computational power of quantum chips to accelerate deployment of quantum computing in the near term. Rigetti deploys full-stack solutions for this integrated computing environment.

Rigetti designs and manufactures superconducting quantum integrated circuits at their in-house fabrication facility. The company packages and deploys those chips in cryogenic environments and build s software that integrates their systems directly into cloud infrastructure.

Rigetti's quantum-first cloud platform provides dedicated access to their quantum hardware through a virtual development environment. Quantum Cloud Services is the company's quantum-first integrated cloud platform that gives users access to their real quantum hardware through a virtual programming environment. It allows the user to develop and execute quantum-classical programs in a virtual, classical compute environment.
