Which Industries Win by 2033, and How to Tell
A two-question screen for quantum advantage by 2033, worked through nitrogen fixation and derivative pricing, plus what would change the answer.
Who Wins If Neutral Atoms Win: Mapping a Modality’s Supply Chain
Neutral-atom machines have no cryostat and no fabricated qubit chip. Almost everything hard about them is optical. A worked map of the bottlenecks, and…
Evaluating a Quantum Company: The Technology
Qubit count is the easiest number to quote and the least informative. A working guide to the metrics, modalities, and manufacturing questions behind a…
Evaluating a Quantum Company: The Claims
A quantum performance claim is scoreable when five things are present: the unit, the population, the conditions, the baseline, and the witness. Here is…
How to Read a Logical Qubit Claim
Vendors report logical qubit counts that are not comparable to each other. The mechanism underneath the number, and the five properties that make two…
NISQ, FTQC, FASQ: How to Read the Three Eras of Quantum Computing
One vendor announces 1,121 qubits. Another announces 48 logical qubits on 280 atoms. Three acronyms explain why those numbers cannot be compared, and what…
A Map of Quantum Computing Modalities
Qubit counts are not comparable across platforms. A framework that separates the computational models from the physical carriers, and identifies which numbers actually differentiate…
A Baloney Detection Toolkit for Quantum Claims
Overstated quantum claims rarely contain a lie. They swap one thing for a similar-sounding thing. Six substitutions, and the questions that catch each one.
How Quantum Error Correction Actually Works
Bit flips, phase flips, stabilizers, thresholds and the arithmetic behind million-qubit roadmaps. A ground-up walkthrough of quantum error correction for engineers.
The Machine Itself
Why the headline qubit count misleads: decoherence, error correction that never reads your data, and the gap between today's hardware and a CRQC.
