Cal’s quantum connection: Scientists linked to UC Berkeley share Nobel Prize in Physics

Three physicists with ties to University of California, Berkeley have won the 2025 Nobel Prize in Physics for their groundbreaking work showing that quantum effects can occur in systems large enough to hold in your hand.

The Royal Swedish Academy of Sciences announced Tuesday that it awarded the prize to John Clarke, a UC Berkeley professor, and John Martinis, a UC Santa Barbara professor who got his doctorate degree from UC Berkeley. Michel Devoret, a professor at Yale University and UCSB, also shares the award with Clarke and Martinis.
