The Foundry’s Hidden Supply Chain: Who Really Wins If Silicon Spin Quantum Computing Wins
In September 2025, a team from the Australian startup Diraq and Belgium's imec published a result in Nature that no one in the semiconductor industry could ignore. They had fabricated silicon quantum dot spin qubits on imec's industrial 300-millimeter wafer…

The Tweezer Array’s Hidden Supply Chain: Who Really Wins If Neutral-Atom Quantum Computing Wins
In 2025, a team at Harvard, MIT, and QuEra did something that no quantum computing platform had done before: they ran a 3,000-qubit atom array continuously for over two hours, replenishing lost atoms mid-computation - effectively building the first quantum…

The Fab’s Hidden Supply Chain: Who Really Wins If Photonic Quantum Computing Wins
In February 2025, a team of more than ninety researchers published a paper in Nature describing something the photonic quantum computing community had been waiting a decade to see: a complete quantum photonic technology stack - single-photon sources, superconducting detectors,…

The Optical Table’s Hidden Supply Chain: Who Really Wins If Trapped-Ion Quantum Computing Wins
In September 2025, IonQ paid $1.075 billion for a company called Oxford Ionics that had built precisely one quantum computer. It wasn't the qubit count that justified the price tag. Oxford Ionics held fewer than two dozen qubits at the…
