The first industrial revolution was accompanied by the emergence of the School of Engineering, the second brought about the School of Electrical Engineering, and the third digital revolution led to the School of Information. It is now obvious that the change in this quantum revolution must lead to the emergence of the School of Quantum Science and Technology. Quantum technology can develop comprehensively through the integration of science, technology, engineering, art and mathematics (STEAM). In 1925, Heisenberg developed the Matrix Mechanics, cracking the mysteries of the Quantum world. Coinciding with the 100th anniversary of Matrix Mechanics, in 2024, the General Assembly of the United Nations proclaimed 2025 the 'International Year of Quantum Science and Technology, ' along with a year-long initiative celebrating the profound impacts of quantum science on technology, culture, and our understanding of the natural world.This book outlines the importance of the 'Second Quantum Revolution, ' introduces quantum computers, quantum communications, and quantum sensors, and then provides a framework for the emergence of the quantum Internet of Things. What basic quantum literacy should modern citizens have in this era? The 'Second Quantum Revolution, ' where quantum knowledge and engineering technology are once again combined, will provide faster, more effective, and more sensitive quantum facilities to accelerate cross-field exploration, and will also make human life more comfortable and convenient than ever before.In the 'First Quantum Revolution' in the 20th century, humans learned quantum science from nature and used existing materials to make quantum components.

In the 'Second Quantum Revolution' in the 21st century, humans further used quantum science to construct quantum engineering. We now make materials and components that are not found in nature and assemble new quantum machines to benefit mankind! This is the stage of a glorious quantum era, which is a hundred times more brilliant than the past classical physics era.
