Chapter 02 · Foundations
Qubits & single-qubit gates —
the linear algebra that actually matters.
By the end of these ten slides you will have written your first quantum operation in Qiskit — and you will know exactly what superposition is, what it does, and what it is not.
What you will learn
Qubit as a unit vector in C²
Pauli & Hadamard, on paper and in Qiskit
Superposition ≠ classical probability
