He founded and led organizations that interfaced with corporate partners such as Google, Amazon Web Services, Microsoft Azure, IBM, and Intel. His entrepreneurial activities connected him with investors and incubators including Andreessen Horowitz, Sequoia Capital, Khosla Ventures, Y Combinator, and GV (company), and with innovation programs at Lawrence Berkeley National Laboratory, Argonne National Laboratory, Fermi National Accelerator Laboratory, and Oak Ridge National Laboratory. Rigetti has appeared at conferences and forums like CES, TED, SXSW, IPAW, and Quantum Tech, and has been part of collaborations involving companies such as D-Wave Systems, IonQ, Xanadu (company), PsiQuantum, and ColdQuanta.

Rigetti Computing

Rigetti founded a company that developed superconducting quantum processors and provided cloud-accessible quantum services, positioning itself alongside firms such as IBM Quantum, Google Quantum AI, Honeywell Quantum Solutions, and Rigetti competitors. The company built hardware integrating components from suppliers and partners including Applied Materials, L3Harris Technologies, Keysight Technologies, TE Connectivity, and Lam Research. Its platforms combined cryogenic systems from vendors like Bluefors, Oxford Instruments, and Cryomech with control electronics referencing products from NI (National Instruments), Analog Devices, Xilinx, and Rohde & Schwarz. The company offered cloud access interoperable with toolchains inspired by standards from Qiskit, Cirq, OpenQASM, ProjectQ, and Forest (Rigetti), and collaborated with academic programs at MIT Lincoln Laboratory, Harvard-Smithsonian Center for Astrophysics, Imperial College London, University of Waterloo, and ETH Zurich.

Research and contributions

Rigetti's technical work focused on superconducting qubit design, microwave engineering, and quantum-classical control systems, drawing on foundational results from researchers at Yale University (transmon qubits), UC Berkeley (circuit QED), University of California, Santa Barbara (coherence studies), and NIST. His contributions relate to topics explored in papers from groups at Caltech, Princeton University, Harvard University, Columbia University, and University of Chicago, and intersect with methodologies used in experiments at Los Alamos National Laboratory and Sandia National Laboratories. He engaged with software and benchmarking efforts similar to those by teams at IBM Research, Google Research, Microsoft Research, Amazon Science, and Rigetti competitors, and contributed to frameworks for error characterization, gate calibration, and noise mitigation paralleling work from ETH Zurich, University of Innsbruck, Max Planck Institute for Quantum Optics, and University of Oxford.

Awards and recognition

Rigetti has received attention from technology press and industry awards, appearing in lists and events alongside honorees from Forbes, MIT Technology Review, Wired, The New York Times, and The Wall Street Journal. He and his company were recognized by programs and competitions associated with DARPA, National Science Foundation, Department of Energy, Department of Defense, and European Commission initiatives, and engaged with standards bodies and consortia such as IEEE, NIST, ISO, Quantum Economic Development Consortium, and Quantum Industry Canada. His public profile has included speaking invitations from World Economic Forum, Council on Foreign Relations, Brookings Institution, Carnegie Endowment for International Peace, and Brookhaven National Laboratory.
