I build automation systems and I am teaching myself quantum computing in public. Honest proof of work from zero: the math, the Qiskit, the noise on real machines.

    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.

    I Just Earned My Second IBM Quantum Badge, and It Says Advanced

    My first IBM Quantum badge said Intermediate and it bent my brain. The second one says Advanced. It is about the algorithms that actually run on today's noisy quantum machines, and I am a self-taught builder who was not supposed to get here.

    I Just Earned My First IBM Quantum Badge and I Am Not Going Back

    There is a type of computer that holds every possible answer at once and only picks one when you force it to look. I found it a few weeks ago. I have not slept well since. First IBM Quantum badge earned. The chapter starts here.
