Learning Outcomes

On successful completion of this module students should be able to:

Decide if a given pure state is entangled.

Describe Bell's setup.

Apply two qubit gates to pure states.

Describe basic quantum information protocols.

Compare classical and quantum information.


The aim of this module is to introduce advanced concepts of classical and quantum information theory. This interdisciplinary subject will broaden the students perspective of the interplay between applied mathematics, computer science and physics.

Brief description

The course will be guided by the question 'what is quantum information useful for?. We will introduce the important concept of entanglement and show how it gives rise to new ways of processing information, such as quantum computation and communication.


Schmidt decomposition.

Entanglement of pure states.

Singlet states and Bell's theorem.

Two qubit gates.

Teleportation, Dense coding, Quantum Information.

Quantum cryptography: BB84.

Quantum algorithms: the gate model.

Introduction to Deutsch-Jozsa & Shor algorithm.

Application of Number Necessary throughout.
Communication Written answers to exercises must be clear and well-structured. Good listening skills are essential to progress in this course.
Improving own Learning and Performance Students will be expected to develop their own approach to time-management in their attitude to the completion of work on time, and in doing the necessary preparation between lectures.
Information Technology Work will be set which requires the use of library facilities.
Personal Development and Career planning Completion of tasks (exercise sheets) to set deadlines will aid personal development.
Problem solving An exercise sheet will be set for each of the exercise classes and selected exercises marked.
Research skills Students will be expected to use the written resources to find supplementary material.
Subject Specific Skills Broadens student knowledge of topics in applied mathematics, computer science and theoretical physics.
Team work Students will be encouraged to work together on questions during the exercise classes.
