Illinois Governor J.B. Pritzker is asking state legislators for half a billion dollars for quantum technologies in the proposed budget he released Wednesday—the latest show of support for a regional quantum ecosystem that has attracted millions of dollars in corporate and government investment in recent years and is emerging as a central driver of U.S. leadership in the field. In an interview with Axios, Pritzker said his proposal includes $200 million for a cryogenic facility needed to keep quantum computing systems cool and $100 million for the development of a quantum campus.
