The Infrastructure Beneath the Qubit: Four Enabling Technologies That Will Determine Which Quantum Computers Actually Scale
Quantum computing captivates with its physics: superposition, entanglement, interference. The companies that build qubits get the headlines, the funding rounds, and the breathless media coverage. But the companies that build the infrastructure beneath the qubits - the electronics that control…

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…

Experimental Quantum Error Correction Below Threshold
When Harvard’s neutral-atom team quietly dropped their new paper on a fault-tolerant architecture for universal quantum computation, a few days ago, it felt like the field had crossed an invisible line. For years we’ve had impressive pieces of the puzzle…

A Quantum Contrarian Con Artist
In the growing spotlight on quantum technology, a new kind of opportunist is taking the stage - the contrarian con artist. These are not the honest skeptics who ask hard questions in good faith. They are bad-faith actors cloaking themselves…

Quantum Computing Due-Diligence: A Field Guide to Evaluating Startups, Technologies, and Claims
Over the years, I’ve developed a personal toolkit - a field guide - for evaluating quantum startups and their claims. The goal is to neither be swept up by the mystique nor dismiss genuine progress. This balance is crucial: the…

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…
