Introductory description

We live in what is often dubbed ‘the information age’. Underlying this is immense computational capability. But what are the limits of computation? What do the laws of physics have to say about that?

This module will introduce quantum computation and show that the laws of quantum mechanics can provide additional computational capabilities. We will show how this can be used to solve certain problems more efficiently. We shall study what quantum computers can offer for simulations in physics and chemistry.

Quantum computing started as an idea in physics but quickly developed into a major interdisciplinary endeavour involving mathematicians, computer scientists and others. This module looks, from the physicist's perspective, at how quantum states and operations on quantum states encode and process information.
