The quantum-computing power of IonQ Inc. could eventually be put to work in some of SoftBank Group Corp.’s portfolio companies as part of a recently-announced strategic partnership with the tech investor.

SoftBank Investment Advisers, which runs its SoftBank Vision Funds 1 and 2, has taken a “large” equity stake in the College Park, Md.-based startup, though not a majority stake, said Peter Chapman, chief executive of IonQ, without giving specifics.

IonQ is SoftBank’s first investment in quantum computing, said Kirthiga Reddy, partner at SoftBank Investment Advisers.
