QCE25 Tutorial 20 - Electrical Circuit and Qubit Interactions in Superconducting Qubits

(only Parts I, V, and VI are recorded in this video) Electrical engineers play a critical role in quantum computers. This is because a quantum computer is just an array of passive qubits controlled by sophisticated classical electronics. Low-power, high-speed, low-noise, and integrated circuits are essential for building future large-scale quantum computers. However, many electrical engineers are unaware of their pivotal role in quantum computing. Many outstanding circuit designers and microwave engineers are also unaware of the basics of quantum computers and the interactions between qubits and control circuits. This tutorial aims to educate engineering communities by bridging the aforementioned knowledge gap, simplifying complex quantum mechanics theory into a language familiar to engineers. The tutorial has 6 sections (each 30 mins). In section I, an overview of qubit operations and the role of control electronics will be discussed. In sections II-IV, the operation of Si qubits and the corresponding classical control and detector circuits (e.g. DAC, TIA, RF reflectometry) will be covered. In sections V-VI, we will discuss superconducting (SC) qubit operations and qubit interaction with classical electronics. Particularly, we will highlight common microwave components on SC qubit-integrated chip and their roles. The authors have offered the same tutorial in QCE 2024 with many enthusiastic attendees. In this tutorial, the content will be improved based on the feedback received and a new textbook published.
