Free Quantum Courses and Textbooks: A Verified Reading List
The good news first
Quantum computing used to be locked behind graduate physics departments. In 2026 you can go from curious to writing circuits using free material. This guide lists resources we actually checked, says what each one is good for, and flags the ones you should treat with care. If you want the big-picture ordering of topics, start with the learning path and come back here for specific picks.
Interactive courses
IBM Quantum Learning. The old learning.quantum.ibm.com address now redirects to quantum.cloud.ibm.com/learning. The landing page features Basics of Quantum Information taught by John Watrous and Use a quantum computer today with Olivia Lanes, and mentions a library of more than ten courses. The page we read did not state pricing, so check the course pages themselves before assuming anything. The practical advantage is that the lessons sit next to the tools you will use later on IBM's hardware.
PennyLane Codebook. PennyLane lists modules you can take one at a time or along a guided path, each mixing theory with exercises. Reported modules include PennyLane Fundamentals, Introduction to Quantum Computing, Single-Qubit Gates, Circuits with Many Qubits, Noisy Quantum Theory, Quantum Error Correction, Grover's Algorithm, the Quantum Fourier Transform, Shor's Algorithm and Variational Quantum Algorithms. The page did not state a price, so verify on the site.
Lecture notes and books you can read for free
- Ryan O'Donnell, CMU 15-859BB (2018). The course page lists the instructor and links PDF notes for Lectures 1 to 25 on quantum computation and quantum information. It is a computer-science flavored route, great if you like proofs and algorithms.
- John Watrous, The Theory of Quantum Information. Published by Cambridge University Press in April 2018. The author's page offers a free manuscript PDF for personal use only, and says the official edition should be bought from the publisher or retailers. This one is mathematical and rewards patience.
- Qiskit textbook (old). The original Qiskit-Community textbook repository carries a notice that it is for an old version and is deprecated, and it was archived on Nov 5, 2024. Do not build a study plan on it. Use IBM Quantum Learning for current material.
The classic that is not free
Nielsen and Chuang, Quantum Computation and Quantum Information. Cambridge University Press, first edition 2000 and a second edition in 2010, nicknamed "Mike and Ike" after the candy. It is still the standard reference many courses assume. You will need to buy it or borrow it from a library. You do not need it to start, but it is a satisfying goal once the basics click.
A sample 12 week plan
| Weeks | Goal | What to use |
|---|---|---|
| 1 to 2 | Linear algebra refresh: vectors, matrices, complex numbers | Any free linear algebra course; Watrous' early chapters later |
| 3 to 5 | Qubits, gates, measurement (qubits, gates) | IBM Basics of Quantum Information, PennyLane Codebook early modules |
| 6 to 8 | Algorithms (Grover, Shor) | Codebook algorithm modules, O'Donnell notes |
| 9 to 10 | Noise and error correction (NISQ, error correction) | Codebook noise and QEC modules |
| 11 to 12 | Run a real circuit and write up what you saw | See hardware access compared |
Honest tips
Do the exercises. Reading about superposition feels like understanding until you try to compute a measurement probability by hand. Keep a short notebook of questions and use the glossary for vocabulary. Be skeptical of any course promising you will become a quantum expert in a weekend, or tying learning to a token. The QNT memecoin has nothing to do with these courses or with Quantinuum Ltd, and nothing here is financial advice.
The field needs people who can explain it plainly, and the front door is wide open. Pick one resource, finish it, then pick the next.

Frequently asked questions
Can I really learn quantum computing for free?
Yes for the fundamentals. IBM Quantum Learning, the PennyLane Codebook, O'Donnell's lecture notes and Watrous' free manuscript cover a lot. Check each site for current pricing.
Is the Qiskit textbook still good?
The old Qiskit-Community textbook repo is marked deprecated and was archived on Nov 5, 2024. Use IBM Quantum Learning instead.
Do I need Nielsen and Chuang?
No, but many courses assume it. It is a paid book from Cambridge University Press, first published in 2000.
Do I need a physics degree?
Not to start. Linear algebra and some programming get you far. Deeper research roles often want more.
