Public milestones
No milestones are listed yet. Milestone claims are only published here with an evidence tag (peer-reviewed / preprint / vendor / disputed) and a primary source: entries are added as they are verified, never generated.
The modality it bets on
Strengths: Fast gates; Semiconductor-style fabrication; Mature ecosystem. Challenges: Cryogenics; Wiring; Crosstalk; Coherence.
Investor lens: a company profile is not a recommendation. The diligence questions that matter (differentiation, full-stack dependencies, manufacturing path, benchmark transparency) are on Evaluating claims.
