The mathematics behind the Bloch sphere: how the angles θ and φ map to quantum state vectors, why single-qubit gates are rotations, and how to read any single-qubit state geometrically.
A clear explanation of the fundamental quantum gates, Hadamard, Pauli, CNOT, and Toffoli, with circuit diagrams and what they actually do to qubit states.
Understand quantum gates as 2x2 unitary matrices, see the explicit matrices for X, Y, Z, H, S, and T gates, and learn how matrix multiplication corresponds to running gates sequentially.
