Pre-requisite qualificationsThis is an applied Theoretical Quantum Physics course, which provides a different insight into quantum physics than the traditional approach. Instead of studying quantum mechanics and the energy-level structure of particles in different ypes of potentials, we look into light-matter interactions on the level of single atoms and single photons. The course lays the foundations for the more advanced Quantum Field Theory course in Year 4.

This module is not approved as a discovery module
Module summaryThis course gives insight into the quantum mechanics of open quantum systems. It studies the interactions between light and matter on the level of single photons and single atoms and introduces concepts that are widely used in quantum optics as well as in condensed matter physics and quatum field theory.
ObjectivesOn completion of this module, students should be able to:
- describe the scattering of single photons through linear optics networks.
- transform a Hamiltonian into an appropriate interaction picture.
- know different methods to coherently control atomic systems with external laser field.
- have a basic idea of the quantisation of the electromagnetic field in free space and inside an optical cavity.
- model the spontaneous emission from an atom of photons using rate equations, quantum jump approach and master equations.
- explain laser cooling.
Demonstrate an understanding of most fundamental laws and principles of quantum physics, along with their application to a variey of areas in quantum physics, some of which are at (or are informed by) the forefront of the discipline;
Solve advanced problems in physics using appropriate mathematical tools;
Use mathematical techniques and analysis to model physical behaviour and interpret mathematical descriptions of physical phenomena.
A variety of methods is introduced to model the dynamics of open and closed quantum systems.
1. Introduction- Dirac notation, interaction and Heisenberg picture, photon scattering in linear optics networks.
2. Manipulation of single atoms- Ion trapping, laser interactions, different ways of manipulating atomic states.
3. Photons and phonons- Quantum harmonic oscillators, phonons, the free radiation field, optical cavities, photon number and multi-photon states.
4. Atom-field interactions- Atom-cavity interactions, single photons on demand, atom-phonon interactions, laser cooling of trapped ions.
5. Spontaneous photon emission- Density matrices, rate equations, a quantum jump approach master equations.
