Bull case
▲ upsideMicrosoft endorsement + telecom-native distributed architecture uniquely positions Photonic for networked quantum data-centers vs standalone machines. $200M+ round in Jan 2026 at $2-2.7B valuation. TELUS partnership for telecom integration. UK Quantum Fund participation Feb 2026.
Bear case
▼ downsideT-centre silicon photonics is the least technologically mature of any QBI Stage B modality; only 3-qubit register demonstrated (Jan 2026, Nature Nano). Gap from 3 qubits to fault tolerance is largest in the cohort.
