Quantum Computing Basics
What quantum computers are, how they work and where the technology stands today.
Entanglement And Interference: The Two Ideas Behind Quantum Algorithms
Entanglement links qubits so they can only be described together. Interference steers the odds towards the right answer. Here is how both work, without the mysticism.
Gates, Circuits And What Quantum Computers Will And Will Not Be Good For
How quantum programs are built from reversible gates, which problems have known quantum speed-ups and why most everyday computing will stay classical.
Noise, Error Rates And Why Error Correction Decides Everything
Qubits make errors constantly. This article explains physical and logical qubits, the error threshold and how to read error correction results from Google, Harvard, Quantinuum and others.
The Hardware Zoo: Six Ways To Build A Qubit
Superconducting circuits, trapped ions, neutral atoms, photons, silicon spins and topological qubits each trade speed, quality and scale differently. Here is how they compare as of October 2026.
Quantum Advantage, Supremacy And The Claims That Did Not Survive
Since 2019, several claims that a quantum computer beat every classical computer have been narrowed or challenged. Here is the record, and how to judge the next claim.
Reading Quantum Roadmaps: What Breaking Encryption Would Take
How to read vendor roadmaps, what a cryptographically relevant quantum computer would need, how far today's machines are from it and why security timetables do not wait.
Seven Quantum Computing Myths For Executives
Quantum computing headlines mix real progress with hype. These seven common myths, and what the evidence actually says, will help leaders set sensible priorities.
