# PsiQuantum The most-funded private quantum pure play (>$1.8B raised; ~$7B valuation after a [[BlackRock]]-led $1B Series E in September 2025, with NVIDIA's venture arm and Qatar's QIA participating). Skips small demos entirely, betting on silicon photonics at million-qubit scale, with government-backed Quantum Compute Centers under construction in Brisbane, Australia (AU$940M) and Chicago's Illinois Quantum & Microelectronics Park. > Status: stub — expand with the photonic architecture bet, the Australia/Illinois subsidy deals, and sovereign-wealth investor angles. ## See Also - [[Quantum Computing Sector]] - [[Qubit]]
