    The tensor product: why 10 qubits means 1024 numbers

    One humble operation builds the space that every multi-qubit state lives in, and explains the exponential. Two qubits in, four amplitudes out.

    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.

    Entanglement, explained without the spooky

    The Bell state in two lines of code, what correlated really means, and why none of it sends messages faster than light.

    Six defects in a verified n8n node for IBM Quantum

    It passed n8n verification with green tests and 98 percent coverage. Then 121 seconds of real QPU time found what none of that could.

    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 NumPy.
