Quantum Computing For Everyone - An Introduction
Fractal Analytics (Srinjoy Ganguly, Shalini Devendrababu)
Fractal Analytics on Coursera, for beginners. Two modules: history and theory, then qubits, gates, and circuits in Qiskit.
Quantum computing education
Quantum computing, from your first qubit to your first job.
An index of quantum computing courses, tutorials and reference material. 112 courses from 13 providers, 220 tutorials with code you can run, and 241 terms defined.

Three ways in. Take the one that matches what you already know.
- No maths required
Start from nothing
What to read first, and what to leave until the notation is familiar. Read the guide - Hands on
Write your first circuit
Qiskit tutorials, beginner projects and exercises that need no quantum hardware. Read the guide - Hardware
See what the machines are
Superconducting, trapped ion, photonic, neutral atom and annealing, compared. Read the guide
Courses
What each one costs, how long it runs and the level it assumes, so you can rule one out before you spend an evening on it.

All 220 tutorials- 01 Julia intermediate Quantum Computing in Julia with Yao.jl Write your first quantum programs in Julia with Yao.jl: build a Bell state, apply gates and rotations, measure, and compute expectation values. Every snippet is run on Yao 0.9. 20 min read

02 Concepts intermediate Measurement, Decoherence and What the Bloch Sphere Cannot Show You The Bloch sphere is a map with edges. This final part covers what measurement does to the arrow, why real qubits drift inside the ball, and why an entangled qubit has no arrow at all. 16 min read -
03 Concepts intermediate Rx, Ry and Rz: Reaching Any Point on the Bloch Sphere Give a rotation a dial instead of a fixed angle and you can steer a qubit anywhere on the Bloch sphere with two gates. This is the Euler decomposition, and it is what your transpiler does to every circuit you run. 15 min read -
04 Concepts intermediate Turing Machines, Computability, and What Quantum Computing Actually Changes A quantum computer computes exactly the same set of functions as a Turing machine, no more and no fewer. It cannot solve the halting problem. What it changes is efficiency, not computability, and this tutorial draws the line precisely. 18 min read - 05 Concepts beginner Hadamard, S and T on the Bloch Sphere The Hadamard gate is a half-turn about a diagonal axis, and S and T are partial twists about the vertical one. Seen on a live Bloch sphere, the H, S and T gates stop being matrices and start being furniture-moving. 14 min read

06 Concepts beginner Pauli Gates as Rotations: X, Y and Z on the Bloch Sphere Watch the X, Y and Z gates run on a live Bloch sphere. All three are half-turns around an axis, which explains why X flips a qubit, why Z appears to do nothing, and why applying any of them twice gets you back where you started. 13 min read
Interactive
Four things on this site you use rather than read. All of them run in the browser, with nothing to install.
The unusual one
Qubit Factory
A qubit rides an assembly line through gate machines while you watch, and the Reader at the end collapses it. Ten exhibits, from a single bit flip up to a pair of belts that always disagree. No score and no timer, and each exhibit opens its circuit diagram once you have run it.
