For the past however-many years, Artur Ekert has been teaching the masters course “Introduction to Quantum Information” at the University of Oxford. During this time, many versions of accompanying lecture notes have come and gone, with constant improvements and changes being made. The version that you will find on this website has been carefully edited by Tim Hosgood into a cohesive “book”, containing additional exercises and topics. Thanks go to Zhenyu Cai for many helpful comments and corrections, and we also appreciate the work of Yihui Xie in developing the Bookdown package with which this document was built.
