In Business Madison: UW research and startups propel quantum innovation

Quantum innovation is nothing new to Mark Saffman — a physics professor at the University of Wisconsin-Madison who has conducted research on a key technology behind quantum computing for over two decades — but he believes the competition for capital and talent is hotter now than ever before.

Since 2018, Saffman has been on the leadership team of Infleqtion, a Colorado-based quantum company that went public in February and has offices in Madison, Chicago and across the globe. The company uses neutral atom technology, Saffman’s specialty, for quantum computing, networking, sensing and security.

Neutral atoms function as the building blocks for quantum computing and sensing — much like the foundational “bits” of traditional computers. But quantum computers have the potential to solve problems of exponentially higher complexity than conventional machines.
