The Willow chip is a major step on a journey that began over 10 years ago. The vision was to build a useful, large-scale quantum computer that could harness quantum mechanics — the “operating system” of nature to the extent we know it today — to benefit society by advancing scientific discovery, developing helpful applications, and tackling some of society’s greatest challenges. As part of Google Research, the team has charted a long-term roadmap, and Willow moves us significantly along that path towards commercially relevant applications.
