| Description:
| Aims: The aim of this unit is to increase the breadth and depth of students' knowledge and understanding of quantum physics, in both fundamental aspects of quantum mechanics and modern applications of quantum theory. Learning Outcomes: After taking this unit the student should be able to: * explain in detail the salient differences between classical physics and quantum physics; * demonstrate an in-depth understanding of the realm of quantum optics and its major applications and frontline research; * give a mathematical description of the quantum principles of vector states, Hilbert space and quantum interference; * use and apply Dirac formalism to light-matter optical phenomena; * explain optical absorption and refraction using a quantum framework; * outline and critically assess the following major applications of coherent light-matter interactions; Rabi oscillations, Ramsey interference, electromagnetically induced transparency and laser cooling; * discuss the principles of quantum cryptography and computing. Skills: Numeracy T/F A, Problem Solving T/F A.
