Who it's for
No code needed. Nothing skipped.
Anyone curious about quantum physics, with no prior knowledge needed. Each lesson can be followed by a non-physicist, and the precise part is there for engineers.
The promise
“By the last lesson you can explain the rules of the very small, how qubits and quantum computers work, and what they can and cannot do.”

How every lesson works
01
The simple picture
Every lesson opens with a picture anyone can follow.
02
The logic chain
Then the reasoning in small steps, with each term explained as it appears.
03
Where you see it
Real things in your life that depend on this idea.
04
Try it
A free simulation or a few lines of Python in your browser.
05
Check yourself
A few questions. If you can explain the answers to a friend, move on.
