We have seen that in order to measure one qubit, a resonator coupled to it is used. When having multiple qubits, resonators with different resonance frequencies are needed. Can you identify each qubit and its resonator in the circuit shown during the video? We see in the picture there are more resonators than qubits, what do you think is the purpose of these?
The extra resonators are for coupling. This way two-qubit operations can be implemented.
