Quantum Leap

This book presents a series of breakthroughs in the field of quantum science and systematically expounds the current frontier issues of quantum information technology being addressed in China. It comprehensively presents a vigorous picture of quantum science from four aspects: basic experiments, quantum communication, quantum computing, and quantum precision measurement. The book deals with the basic physics experiments of quantum information, focusing on quantum entanglement and quantum measurement randomness. It also summarizes the principles and development of quantum key distribution and introduces the schemes and technologies used in practical quantum key distribution. Various physical systems in quantum computation and quantum simulation are introduced, and an overview of quantum precision measurement is given. The authors include world-leading specialists in the domain as well as young active researchers. Researchers, teachers, and undergraduates majoring in physics will find this book helpful. It is also used as a reference work for other science majors and other academics interested in quantum science.
