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…

The Chandelier’s Hidden Supply Chain: Who Really Wins If Superconducting Quantum Computing Wins
In September 2025, Bluefors - the Finnish company whose cryogenic systems cool most of the world's superconducting quantum computers - signed a deal to buy up to ten thousand liters of helium-3 per year. The supplier? Interlune, a Seattle startup…

Cisco’s Full-Stack Approach and the Road to Quantum Data Centers
Cisco took on an ambitious full-stack strategy to make distributed quantum computing a reality sooner than many expect. Instead of waiting for a single perfect quantum processor with millions of qubits, Cisco is building the hardware, software, and architecture needed…

Factoring RSA-2048 in 20 Minutes with 42 Qubits
We present a resource estimate for factoring 2048-bit RSA integers using a quantum computer with just 42 physical qubits and a runtime of approximately 20 minutes. Our approach combines well-established results from the recent literature: Regev's O(n3/2) quantum factoring algorithm…

The Easiest Job in Quantum Computing – Being a Cynic
Don’t mistake the noise of cynicism for the signal of intelligence. If someone validates themselves as a useless cynic - unwilling to provide anything beyond scoffs and derision - don’t waste your energy getting dragged into their performative pessimism. Instead, direct…

Why Companies May Need a Chief Quantum Officer (CQO)
In my opinion, forward-thinking organizations should consider creating a Chief Quantum Officer (CQO) role. Much like those historical electricity executives, a CQO would spearhead the adoption of a disruptive technology that is revolutionary, promising - but widely misunderstood. It’s a…

Magic States: A Key to Universal Fault-Tolerant Quantum Computing
Magic states are special quantum states that enable the universal operations needed for any quantum algorithm, yet which are not themselves easy to produce or protect. In essence, magic states supply the "extra quantum sauce" that elevates a protected quantum…

The Nervous System of Quantum Computing: A Deep Dive into Quantum Control Systems
In July 2025, Keysight Technologies shipped a piece of equipment to a research institute in Tsukuba, Japan, that most people outside the quantum industry had never heard of - yet without it, the 1,000-qubit quantum computer it was destined for…

What It Will Actually Cost to Break RSA-2048: Energy, Hardware, People, and the Bill Nobody’s Talking About
Breaking one RSA-2048 key on a CRQC could cost $2–5 million when you add up energy, amortization, personnel, and facilities All three approaches share silicon's core advantages: compatibility with semiconductor industry infrastructure, small qubit footprint (~50 nm), and long coherence…
