Who we are

Rigetti Computing is a full-stack quantum computing company. We design and manufacture superconducting quantum integrated circuits. We package and deploy those chips in a low temperature environment, and we build control systems to perform quantum logic operations on them. We build software to integrate our systems directly into existing cloud infrastructure.

We believe the first useful quantum computers are within reach, and we believe quantum computing has the potential to one day have an enormous positive impact on humanity. To help realize that vision, we also develop new algorithms for quantum computing, with a focus on near-term applications in computational chemistry and machine learning.

Our product, Forest, is the world’s first full-stack programming and execution environment for quantum/classical computing. Forest includes Quil (quantum instruction language), our programming standard for quantum/classical computing.
