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: Room-temperature transmission; Networking potential. Challenges: Photon loss; Deterministic sources; Detectors; Large overhead.
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.
