Learn Quantum Computing with Python and IBM Quantum
By :

So far, you have learned how to create quantum circuits, add gates that manipulate the qubits of the circuit, and execute the circuits. In this section, we’ll go a little deeper to see how a quantum circuit is converted from digital instructions to pulse instructions that physically manipulate the qubits using microwave pulses as instructed by the quantum circuit. Microwave pulses are what manipulate the qubits on quantum devices. A signal is generated and tuned to a specific frequency of each qubit so that the signal only affects the qubit that the pulse is tuned to.
Much of this section will assume that you have some knowledge of signal processing, particularly that of transmon-like superconducting qubits and microwave pulses. For reference, this is a fantastic paper that goes into the details, https://arxiv.org/pdf/1904.06560.pdf, where sections 4.C and 4.D cover a basic overview of how microwave signals are used to manipulate...
