moves to |111⟩ and vice versa. Its matrix will be written like this: EXTRA: CIRCUIT COMPOSITION Serially wired gates Assume that we have two gates A and B, that both act on n qubits. When B is put after A in a series circuit, then the effect of the two gates can be described as a single gate C. C =
