We partner with leading quantum hardware companies and university labs to advance the design, engineering and benchmarking of quantum computers, with a core focus on quantum error correction.

We work with leading industry partners in the pharmaceutical, climate science, advanced materials and aerospace sectors to identify specific areas where quantum computing will drive the greatest advances in human progress.
