  1. LessonComing soon

    From bits to qubits

    What changes when a bit can be more than off or on.

  2. LessonComing soon

    Superposition

    Amplitudes, not maybes: what it really means to be 0 and 1.

  3. LessonComing soon

    The Bloch sphere

    Every single-qubit state, drawn as an arrow on a ball.

  4. LessonComing soon

    Measurement

    Why looking forces an answer, and how to predict the odds.

  5. LessonComing soon

    Reading kets

    |0⟩, |1⟩ and |ψ⟩: the notation, decoded.

  6. CheckpointComing soon
