Introduction to Quantum Information Science
Last updated: 03 February 2023 (see change history)
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 was originally edited by Tim Hosgood into a cohesive “book”, and both authors have since then added extra comments, exercises, and examples.
Although almost complete, this book is still a work-in-progress — a few sections are missing, but we are constantly updating and filling in the gaps! Note that, because of this, external links to specific chapters or sections might break as things move around.
