THE BASIC THEORY OF SUPERCONDUCTING QUANTUM COMPUTING GATE OPERATION AND ITS FIDELITY MEASUREMENT
For the existing superconducting qubit devices,constructing the corresponding high-fidelity gate operation after system calibration is a key step to realize quantum compu-ting.As the fifth chapter of the series of"Introduction to physics frontier—superconducting quantum computing",this paper systematically discusses the physical picture and basic meth-od of constructing superconducting qubit gate operation through microwave pulse,gives a set of construction process of single bit gate operation,and extends the measurement and optimi-zation development of gate operation fidelity.This paper aims to help the physics teachers,senior undergraduates,graduate students,and science and engineering backgrounds interested in superconducting quantum computing readers to systematically understand the whole basic process of superconducting qubit gate construction and gate operation fidelity measurement and optimization.
