Example Concept: Superconducting qubits are controlled by microwave pulses generated by classical electronics, which are converted into analog signals using DACs. These pulses are used to perform quantum gate operations by resonating at the qubit's transition frequency. The readout of qubit states is achieved by measuring the response of a coupled resonator, which is processed by analog-to-digital converters (ADCs) and interpreted by classical systems to determine the qubit state.
