WebThe single argument to QuantumCircuit is interpreted as the number of qubits we want. So this circuit is one that has a single quantum register consisting of three qubits, and no classical register. When adding gates, we can then refer to the three qubits simply by their index: 0, 1 or 2. For example, here's a Hadamard on qubit 1.
