Abstract
This set of lecture notes was prepared for a single-semester junior-level course on the fundamentals of quantum technology offered in the Elmore Family School of Electrical and Computer Engineering at Purdue University. The course is primarily intended to introduce engineering students who have completed courses in linear algebra, differential equations, and basic electrical circuits but with no background in quantum physics to the fundamental concepts of quantum physics needed to prepare engineers to work on the development of quantum information technologies or pursue more advanced studies in this field. Focus is placed on developing an understanding of the basic behavior of quantum systems, the implications of which are discussed in the context of the popular experimental platform of quantized circuits where possible. Topics covered include the fundamentals of the Schrödinger equation and wavefunctions, the general mathematical framework of quantum mechanics, the use of approximate methods for analyzing quantum systems, the quantized interactions between (artificial) atoms and linear circuits, and the density matrix. The course also provides an introduction to revolutionary quantum information technologies such as quantum communication systems, quantum computers, and quantum sensing systems.
