Superconducting Qubit Architecture and Chip Design - QCE Tutorial 2024 Parts V and VI

Electrical Circuit and Qubit Interactions in Silicon and Superconducting Qubits (Part V and Part VI) of QCE 2024 Tutorial 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 necessary to build the future large-scale quantum computers. However, many electrical engineers are not aware of their pivotal role in quantum computers. Many outstanding circuit designers and microwave engineers are also not aware of the basics of quantum computers and the interactions between the qubits and the control circuits. This tutorial is an effort to educate those engineering communities in order to bridge the aforementioned knowledge gap by simplifying complex theory from quantum mechanics 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. Both lectures and demos are included.
