This book is based on the lecture courses taught by Dunningham and Vedral at the University of Leeds. The book contains all the necessary material for quantum physics and relativity in the first two years of a typical physics degree course. The choice of topics complies fully with the Institute of Physics guidelines, but the coverage also includes more interesting and up-to-date applications, such as Bose condensation and quantum teleportation.<BR><BR>"A good, solid and very readable exposition of the subject that will appeal to both students and specialists." Professor Artur Ekert University of Oxford<BR><BR>"This is an ambitious book aimed to provide an introduction to both the revolutionary theories of the twentieth century, quantum mechanics and special relativity, beginning from a historical perspective but advancing to topics of recent interest such as entanglement and quantum computing." Professor Tom Kibble Imperial College London
