About the publication
Quantagram
Quantum computing, cryptography, and their convergence with artificial intelligence — written for readers who want the physics and the engineering, not the hype.
Quantagram covers the ideas, breakthroughs, and open questions shaping the future of quantum technology. The field sits at an unusual moment: the underlying physics is largely settled, the engineering is accelerating, and the gap between what has been demonstrated and what is genuinely useful remains wide. Most coverage collapses that nuance into headlines. Our goal is the opposite — to explain how these systems actually work, what has really been proven, and what remains uncertain.
Every article is built around first principles and concrete detail: the physics of a qubit platform, the mathematics of an algorithm, the exact guarantee a protocol provides. Where a result is contested or a timeline is speculative, we say so plainly.
From Shor’s factoring and Grover’s search to the variational methods (VQE, QAOA) that define the near-term era.
Quantum Hardware6 articlesSuperconducting circuits, trapped ions, neutral atoms, photonics, topological qubits — and the error correction that ties them together.
Quantum Cryptography3 articlesQuantum key distribution (BB84, E91) and the post-quantum cryptography now replacing RSA.
AI Integrations3 articlesQuantum kernels, barren plateaus, and an honest accounting of what the NISQ era can and cannot deliver.
Future Tech5 articlesThe quantum internet, neuromorphic hardware, and the trajectory of the field as a whole.
Physics before hype
We explain the mechanism, not just the milestone. If you finish an article without understanding why something works, we have failed.
Honest about limits
Quantum-advantage claims are examined critically. When classical methods still win, or a result is a proof-of-principle, we say so.
Precise, not vague
Real numbers — error rates, qubit counts, gate fidelities, key sizes — over adjectives. Diagrams convey the actual structure of a system.
Accessible depth
Technical, but written to be followed by any motivated reader. Jargon is defined in the glossary.
Quantagram is written and edited by KhGh, covering the intersection of quantum computing and artificial intelligence. The publication is independent — not affiliated with any hardware vendor, lab, or platform — which is what lets it assess competing approaches on their merits.
