This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a low-slung building in an office park near the southeastern edge of the San Francisco Bay,

This technology isn't ready to go mainstream yet, but getting portfolio exposure to it before that happens could prove a profitable strategy.

Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that it has signed a letter of intent (“LOI”) with the U.S. Department of Commerce (the “Department”) for an award of up to $100 million in funding over three years to accelerate superconducting quantum computing R&D.

Empowered by artificial intelligence technologies, computers today can engage in convincing conversations with people, compose songs, paint paintings, play chess and go, and diagnose diseases, to name just a few examples of their technological prowess.

Therefore, Rigetti can bring new computers to market and commercialize them much faster than its competitors. During the first quarter of 2026, the company made its flagship Cephe

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those promises could be many years away

Quantum computing is emerging as a powerful complement to CPUs and GPUs, with advances in hybrid systems, error correction and exascale integration.
