Under Secretary Gina Raimondo’s reorganized Chips R&D Office, the Commerce Department is reportedly willing to “go deep” in quantum startups – becoming shareholders in exchange for government R&D grantsreuters.comcm.asiae.co.kr.

The quantum proposals would similarly tie about $10 million of support per company to a U.S. equity investmentreuters.comcm.asiae.co.kr.
