PsiQuantum
Building the first commercially useful quantum computer.
About PsiQuantum
Photonic quantum computer using silicon-photonic chips. Goal: 1M-qubit machine by end of decade. Backed by Microsoft, BlackRock.
§ Pitch deck breakdown
How PsiQuantum would pitch themselves.
Target customer
Pharma (drug discovery), finance (portfolio optimization), and materials science enterprises with computational problems unsolvable by classical machines.
Problem they solve
Today's quantum computers have <1K qubits with high error rates — useless for real-world problems. A fault-tolerant 1M-qubit machine would unlock trillion-dollar use cases.
Key differentiator
Photonic architecture is the only quantum approach that scales using existing semiconductor manufacturing (GlobalFoundries partnership). No exotic cooling or vacuum chambers — operates at near-room temperature.
Go-to-market strategy
Government + sovereign deals (Australia $620M commitment) fund the build-out. Once at scale, B2B quantum-as-a-service for pharma + financial-services compute workloads.
