Qiskit

Qiskit as version 2.x works now, not how old tutorials show it. The primitives that replaced execute, and every snippet run before it ever ships.

    I could not find a place to practise Qiskit, so I built one

    Every Qiskit tutorial I found was written for a version that no longer runs. So I built twenty exercises that check your answer by inspecting the objects your code produces.

    Quantum gates are just matrices you can run by hand

    X, H, Z and the rotations: applying a gate is multiplying a matrix by a vector. Literally. Worked by hand, then checked in Qiskit.

    The version trap that cost me an evening (Qiskit 2.x)

    execute() is gone, Aer moved out, and the tutorials never got the memo. What died in Qiskit 2.x and the modern pattern that replaced it.

    The Python you actually need for quantum computing

    Dictionaries for counts, just enough OOP to read Qiskit, and NumPy as the bridge. The thin slice that matters, nothing else.

    A qubit is not a coin under a cup

    The superposition myth, taken apart with math you can run. Not a hidden answer waiting to be read, but something stranger and far more precise.
