Quantum Source Photonic

Photonic FTQC bet on the ORIGIN deterministic-photon source — designed to avoid PsiQuantum's probabilistic-gate overhead.

Photonic FTQC bet on the ORIGIN deterministic-photon source — designed to avoid PsiQuantum's probabilistic-gate overhead.

— Ledger Desk · analyst thesis

Bull case

upside

If the ORIGIN engine produces deterministic photons at demo scale, PsiQuantum partners or acquires; Quantum Source becomes the photonic source IP standard. Potential JV partner in the proposed $200M US-Israel quantum/AI fund.

Bear case

downside

Photonic FTQC is a 2030+ story regardless; cap table is too thin for the capex required at scale; Israeli funding stays research-grade not procurement-grade.

Ledger Score · Quantum Source

The Ledger reads sceptical

The photonic dark horse with a deterministic-photon-source story that could leapfrog PsiQuantum's overhead problem.
