Description
This module explores how light may be controlled and guided at the level
of few photons. It describes how quantum physics may be harnessed in the
future to offer new and exciting opportunities in manipulating light,
including quantum computing and communication. This module will range
over basic physics, mathematical formulation of quantum theory, and
topical applications.
Module Aims
This module aims to develop a detailed understanding of the physics that
underpins quantum optics and photonics, and learn the underlying
mathematical language. It will explores solutions to problems from topics at
the forefront of current optics research, such as the production and
manipulation of light in nonclassical states.
