abstract = {The development of scalable, fault-tolerant quantum computers hinges on the ability to execute quantum logic operations with exceptionally high fidelity. For superconducting circuits, a leading platform for quantum information processing, this necessitates precise control over qubit states using engineered microwave pulses. This report provides a comprehensive framework for understanding the effective control of superconducting qubit systems through heterodyne experimental setups. We begin by establishing the theoretical foundations of qubit-resonator interactions, tracing the progression from the fundamental Rabi model to the practical dispersive Hamiltonian. A model of the heterodyne signal generation and delivery chain is presented, connecting the classical control electronics to the quantum dynamics of the qubit. We systematically categorize and quantify noise sources originating from the control electronics, the quantum system’s environment, and system-level interactions. Finally, we discuss advanced strategies for noise mitigation, including optimal control pulse shaping and dynamical decoupling, and provide practical guidelines for the design, calibration, and operation of high-performance qubit control systems.},
