Bull case

upside

PT-1 photonic system shipped to US Air Force Research Lab + UK MoD; £15M Series A 2022 led by Octopus Ventures. Distinctive go-to-market in quantum-enhanced AI training rather than chemistry/optimization. UK sovereign anchor customer.

Bear case

downside

Hybrid quantum-AI thesis is the most disputed in the sector. Photonic FTQC timeline pushes commercial impact past 2030. Smaller cap relative to peers.

A profile is a snapshot of an argument, not a verdict. The Ledger updates the score nightly; the thesis we revisit only when the facts change.
