PsiQuantum vs Cursor

About

PsiQuantum is a Palo Alto, California-based photonic quantum computing company — backed with $700+ million in total funding including a $1 billion Series E in February 2025 led by BlackRock, Temasek, and Baillie Gifford (with NVIDIA NVentures participation) at a $7 billion valuation — building utility-scale fault-tolerant quantum computers using silicon photonic chip technology manufactured through an exclusive partnership with GlobalFoundries at commercial semiconductor foundries rather than bespoke quantum hardware. In February 2025, PsiQuantum announced the Omega chipset — the first manufacturable chipset for photonic quantum computing, integrating high-performance single-photon sources, superconducting single-photon detectors, and next-generation optical switches with 99.98% single-qubit fidelity and 99.22% two-qubit fusion gate fidelity. PsiQuantum is building Quantum Compute Centers in Brisbane, Australia (backed by A$940 million from Australian and Queensland governments) and Chicago, Illinois, targeting operational systems by end of 2027. Founded in 2017 by Jeremy O'Brien, Terry Rudolph, Mark Thompson, and Pete Shadbolt.
