Quantum Information Theory Nielsen, Chuang

This comprehensive textbook describes such remarkable effects as fast quantum algorithms, quantum teleportation, quantum cryptography and quantum error-correction. Quantum mechanics and computer science are introduced before moving on to describe what a quantum computer is, how it can be used to solve problems faster than 'classical' computers and its real-world implementation. It concludes with an in-depth treatment of quantum information. Containing a wealth of figures and exercises, this well-known textbook is ideal for courses on the subject, and will interest beginning graduate students and researchers in physics, computer science, mathematics, and electrical engineering.

After the first edition of this book was published, I received much positive feedback from the readers. It was very helpful to have all those comments sug­ gesting improvements and corrections. In many cases, it was suggested that more aspects on quantum information would be welcome.
