These are the places where people are learning to turn diamond into computer chips. Yellow dots grow the diamond, pink ones make power switches, purple ones build logic, and blue ones build quantum bits.

Japan dominates wafers and power devices (Saga, AIST, NIMS, Waseda, Ookuma); Europe and the United States lead NV quantum physics (Stuttgart, Delft, Harvard, MIT). Commercial room-temperature NV computing is early and mostly vendor-reported.

Selection follows the evidence table of chapter 10, not a market survey; institutions appear once per headline result. Evidence labels: P peer-reviewed, N news, V vendor statement.
