Quantum computing has emerged as a promising computational paradigm capable of solving certain problems beyond the practical capabilities of classical computers. Although quantum processors rely on quantum mechanical phenomena such as superposition and entanglement but their operation depends heavily on classical electronic systems for control, communication, and measurement. Complementary Metal Oxide Semiconductor (CMOS) technology plays a critical role in providing this electronic infrastructure due to its low power consumption, scalability, and high integration density. This paper explores the role of CMOS-based control electronics in superconducting quantum computing systems and the functions of key components including Arbitrary Waveform Generators (AWGs), Digital-to-Analog Converters (DACs), mixers, transmission lines, resonators, and readout circuits. The paper also examines the emerging field of Cryogenic CMOS (Cryo-CMOS), which aims to improve scalability and reduce latency in future quantum computers. The study highlights how CMOS technology acts as a bridge between classical electronics and quantum hardware.
