FAF015F, 7.5 credits

Valid from: Spring 2015
Decided by: FN1/Anders Gustafsson
Date of establishment: 2014-12-19

General Information

Division: Atomic Physics
Course type: Third-cycle course
Teaching language: English

Aim

The course aims at providing a basic understanding of key concepts in the quantum infromation field, including quantum computers. The basic physics and quantum mechanics is addressed from the perspective of information theory. This enables the course participants to theoretically reflect and through labs and hand in assignments in practice explore possibilities and problems and applying quantum mechanics for information science.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• have acquired a good understanding of single and coupled qubits
• have acquired basic knowledge about quantum gates and elementary quantum circuits
• have acquired an understanding of the basic principles of key quantum algorithms
• have acquired knowledge about physical systems for implementing quantum bits
• have acquired basic knowledge on quantum error correction
• have acquired knowledge about the koncept of entropy in quantum infromation
• have acquired knowledge about the basic principles for quantum teleportation and quantum cryptography

Competences and Skills

For a passing grade the doctoral student must

• have acquired the ability to analyse properties of siple quantum algorithms.
• have acquired the ability to carry out calculations relevant for simple quantum information processes.
• have acquired some experience of experimental manipulation of single quantum bits.

Course Contents

The course starts with a general overview of quantum computation and quantum information (Nielsen & Chuang, "Quantum Computation and Quantum Information", chapter 1) and a recapitulation of the fundamental elements in quantum mechanics (chapter 2) and computer science (chapter 3) needed for the rest of the course. The second part of the course is then focussed specifically on quantum computation, treating quantum gates and quantum algorithms. In particular the quantum Fourier transform that is used in the Shor's algorithm for factorisation of large integers and search algorithms like the Grover's algorithm are treated. Experimental realisation schemes for quantum computers are also treated in this part of the course. Finally a more general treatment of quantum information is given in the last part of the course. Including topics as, the influence of noise on quantum processes, error-correction codes, the connection between entropy and information or more general aspects on quantum information including topics such as quantum communication and quantum cryptography.
