Every Quantum Vendor Measures Progress Differently. That’s the Point.
Quantum vendors report different measures of scale, fidelity, throughput, and logical performance. Each number may be valid, but together they do not form a common scoreboard. Here is why that matters.

I Spent a Year Writing About Europe’s Quantum Failures. Now I’m Moving My Company There.
I've spent the past year documenting Europe's quantum commercialization gap. Now I'm moving Applied Quantum's headquarters from Singapore to the EU. The contradiction is only apparent.

Quantum Computers Are “Always Five Years Away.” The Targets Are Not.
A new philosophical paper explains why quantum-computing timelines keep resetting. The PFYT framework names a real pattern, but it confuses an unsettled architecture with an undefined target.

The Last Unregulated Forecast: Why We Still Pay the Oracle
Croesus paid Delphi before crossing the Halys. Boards pay for value-at-stake slides before funding quantum programs. The need for a number is ancient and human. The exemption from audit is new, and it costs us.

Fidelity in Quantum Computing: The Nines That Decide Q-Day
The best single-qubit gate now fails once in 6.7 million operations. The best two-qubit gates fail a thousand times more often. That gap, counted in nines, sets the pace of fault tolerance and every serious Q-Day estimate.

Quantum Washing: The Quantum Industry’s Credibility Tax
Greenwashing had a decade-long head start and its own SEC enforcement playbook before the quantum industry caught up. Quantum washing is following the same arc, faster, because the underlying science is harder for outsiders to evaluate.

McKinsey’s $600 Billion Quantum Finance Number Doesn’t Add Up. Literally.
McKinsey's Quantum Technology Monitor puts quantum computing's finance value at 400 to 600 billion USD by 2035. The disclosed arithmetic ignores its own assumptions, merges AI with quantum, and is never reconciled with published resource estimates. I checked.

Every US Quantum Computer Runs on Foreign Parts and Foreign Inventions
The U.S. quantum community keeps saying America built every layer of the quantum stack. I tested that claim against the historical record, layer by layer, from theory through cryogenics. The answer has direct implications for supply chain policy and alliance…

Quantum’s SPAC Gold Rush: The 2021 Class Promised $1.2 Billion and Delivered $138 Million
The first quantum SPAC class projected $1.2 billion in 2025 revenue and delivered $138 million. Five more companies have listed through SPACs since January, with at least six queued. I read the new wave against that scoreboard.

Quantum Annealing’s Ideal Form Is the Gate Model in Disguise
A 2004 theorem says the idealized model behind quantum annealing and the gate model are one machine in disguise. Its proof freezes a computation at the bottom of an energy valley, and its fine print keeps annealers away from RSA.

Helium-3 Alternatives: Every Exit From the Shortage, Assessed
Ten engineering escape routes and one geopolitical wildcard for quantum computing's scarcest input, from breeding tritium on purpose to cooling qubits from inside the chip. I assess what each can deliver, what blocks it, and what would change the answer.

Nobody Understands Quantum Mechanics. Everybody Uses It.
A board member accused me of selling a technology nobody understands. He was half right. The interpretation of quantum mechanics is unresolved. The mathematics has been tested to twelve decimal places and runs your phone.

Microsoft’s Majorana Qubit: What the Experts Actually Think
I've never trusted the Majorana story, but I'm no condensed-matter physicist. So after the latest chip and the latest Nature rebuttal, I went looking for where the experts, skeptics and defenders both, actually land.

Quantum Snake Oil Is Flooding the News Cycle — and the Industry Is Letting It Happen
Three extraordinary quantum claims in two weeks, none peer-reviewed, all tied to commercial events. The quantum industry's credibility problem is accelerating, and the people paying the price are the enterprises trying to make real migration decisions.

The Quantum Supply Chain: Where Every Component Comes From and What Breaks If It Stops
A handful of countries and companies supply the entire Western quantum hardware stack. Where the concentration risk sits layer by layer, how it materializes in ordinary procurement, and why open architecture is the structural mitigation.
