Why this person is here

Co-founded PsiQuantum around the premise that a useful machine needs millions of qubits, and that photonic chips made in a conventional semiconductor foundry are the only plausible route there. The company's large financing rounds make this a case where the funding tables and the technical argument have to be read together.

How it connects to the data on this site

PsiQuantum's large private rounds are the clearest case on this site for why a financing valuation is not a market capitalisation and must not be placed in the public-equity table.

Verification status: not verified. A source link is not a verification — the current wording of the affiliation still needs to be checked against an official biography.
