FYST30 Quantum information


The aim of the course is to provide basic knowledge in how quantum systems can be used to carry out general computation algorithms. It also includes a brief treatise of error correction and the influence of noise, as well as a laboratory exercise demonstrating control of a rudimentary quantum system.

Welcome to the introductory meeting for the 2017 course. It takes place March 20th in room C368 at 15.15.

Course contents

The course will be based on and closely follow the disposition of the book Quantum Computation and Quantum Information by Michael A. Nielsen and Isaac L. Chuang.

This book starts with an introductory section containing three chapters. The first chapter is a general overview of quantum computation and quantum information. The second and third chapters recapitulate the elements in quantum mechanics and computer science that are necessary requirements in order to be able to follow the rest of the book.

The second section is focused specifically on quantum computation. It starts with a chapter on quantum gates. The next two chapters treat quantum algorithms. First the quantum Fourier transform that is used in the Shor's algorithm for factorisation of large integers and then search algorithms like the Grover algorithm are treated. This second section then ends with a chapter on schemes for physical realisation of quantum computers.

 The third section is a more general treatment of quantum information. This section among other things contains a treatment of the influence of noise on quantum processes and a chapter on error-correction codes.
