Module aims

  • To complement the traditional approach to quantum mechanics based on particle dynamics.

  • To study quantum mechanics in a finite-dimensional space in its own right.

  • To explain that information is physical and explore the consequences thereof.

  • To introduce basic ideas of quantum computation and quantum information.

  • To see the interplay between mathematics and physics at work in an active research area.

Module learning outcomes

Subject content

  • be familiar with quantum mechanics in finite-dimensional spaces;

  • appreciate the differences between classical and quantum mechanical processing of information;

  • understand paradigms of quantum information theory such as the no-cloning theorem, teleportation and basic quantum algorithms;

  • be able to understand and construct simple quantum circuits;

  • understand what a universal quantum computer is;

  • understand examples of tasks for which quantum protocols can outperform classical ones.

Academic and graduate skills

  • Academic skills: this course requires students to apply abstract mathematical techniques and concepts to describe counter-intuitive physical phenomena.

  • Graduate skills: through lectures, examples, classes, students will develop their ability to assimilate, process and engage with new material quickly and efficiently. They develop problem solving-skills and learn how to attach physical meaning both to previously known and to new mathematical structures.

Module content

[Pre-requisite modules for Natural Sciences students: Maths for the Sciences 3 (MAT00019I), and Quantum Mechanics 1 (MAT00024H).]

In recent years, a quantum mechanical theory of information has emerged. The central idea is that all processing of information, ultimately, requires physical objects to carry it. If implemented microscopically, the quantum mechanical nature of the carriers becomes relevant and must be taken into account. Interestingly, this insight does not limit the possibilities to process information but opens up new, classically unexpected ways to proceed.

The first part of the module presents quantum mechanics in finite-dimensional spaces where most of quantum information processing takes place. Important concepts such as entanglement and Bell inequalities will be introduced. The second part is dedicated to quantum information proper. It includes topics such as quantum circuits, teleportation, quantum cryptography and basic quantum algorithms.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
