    Measurement is not magic: the Born rule by hand

    Why a quantum result is a probability: amplitude squared, worked on paper and checked in NumPy, one basis at a time.

    The density matrix: what the state vector misses

    A pure state fits in a vector. A noisy or entangled one does not. Density matrices, quantum channels, and what they show that vectors miss

    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.
