Quantum computing without the hype
QPU137 is an independent website that teaches quantum computing from zero and tracks real quantum hardware. We are not owned by, paid by, or partnered with any quantum hardware company. Every hardware number on the site links to where it came from and when we checked it.
What does QPU137 offer?
- A hardware catalog — 35 quantum processors and platforms, each figure with its source, date and method. When a company doesn’t publish a number, we say so instead of guessing.
- The Lab — build a quantum circuit, run it on an exact simulator in your browser, and see how it changes on different real chip layouts.
- 9 courses, 101 chapters — from the math and the physics up to algorithms and error correction, written so a curious 13-year-old can follow. Chapter 1 of every course is free.
- Free lessons, algorithms, reality checks and the blog — short, honest answers to the questions people actually search.
Who is QPU137 for?
Developers, students and curious people who want to understand what quantum computers really are — and what they can and can’t do today. You don’t need a physics degree. You need to be willing to run a circuit and look at the result.
Who runs QPU137?
Pattanaik Ramswarup — founder and editor. Pattanaik Ramswarup is a database and DevOps engineer with more than ten years of experience running PostgreSQL and cloud infrastructure, and an AWS Certified Solutions Architect – Associate. He also founded Local AI Master, a site about running AI models on your own hardware. He built QPU137 to be the quantum computing reference he wanted as a developer: plain language, sourced numbers, and circuits you can check yourself.
QPU137 is not run by a physicist, and it doesn’t ask you to trust anyone’s credentials. Instead, every claim is built to be checked: hardware numbers link to their sources, and every circuit prediction is tested against an exact simulation.

How do we check facts?
Every hardware figure carries five things: a source, the date of that source, the date we read it, how it was measured, and whether it is the company’s own claim. We never estimate, fill in or borrow a missing number. Claims about what quantum computers can do are sorted into clear labels — theory, lab demo, hardware demo, practical today, roadmap claim, or disputed — and never blended. The full rules are in our methodology and editorial policy.
Every circuit prediction in the lessons is checked against an exact simulation, and our simulator is tested against Qiskit. When we get something wrong, we fix it in public in the corrections log.
How is QPU137 paid for?
By learners, not vendors. The hardware data, the Lab and the first chapter of every course are free. Pro unlocks the rest of the courses. We take no money from hardware companies, so no company can buy a better ranking — and we don’t publish rankings anyway.
Why the name?
QPU means quantum processing unit — the quantum chip. 137 is roughly the inverse of the fine-structure constant (about 137.036), a number physics measured rather than assumed.
