Nvidia is in advanced talks to invest in quantum computing startup PsiQuantum, according to people familiar with the matter. Palo Alto-based PsiQuantum raised at least $750 million in a round led by BlackRock, with a pre-money valuation of $6 billion. Unlike many quantum startups that rely on unconventional materials, the company uses photons as quantum bits and utilizes standard semiconductor manufacturing methods. The move would mark Nvidia's first direct investment in a company building a physical quantum computer, representing a shift in its strategic focus from previous AI-centric businesses.
