Martinis, Google’s Head of Quantum Computing Hardware, Has Resigned

(Wired) John Martinis, Google’s head of quantum computing hardware has resigned. Martinis brought a long record of quantum computing breakthroughs when he joined Google in 2014. He quit after being reassigned to an advisory role.
After the team had first got its quantum supremacy experiment working a few months earlier, Martinis says, he had been reassigned from a leadership position to an advisory one. Martinis tells WIRED that the change led to disagreements with Hartmut Neven, the longtime leader of Google’s quantum project.
A Google spokesman did not dispute this account, and says that the company is grateful for Martinis’ contributions and that Neven continues to head the company’s quantum project.
Martinis leaves Google as the company and rivals that are working on quantum computing face crucial questions about the technology’s path.
