An Introduction to Quantum Optics


This course aims to provide the fundamental tools and concepts of quantum optics – the field that deals with the quantum description of light. Starting from the concept of the photon, the quantization of the electromagnetic fields, non classical states of light, quantum entanglement and finally the description of quantum light-matter interactions.


1. Brief overview of prerequisite subjects: Fourier, optical modes
2. From Maxwell equations to the uantization of the electromagnetic field
3. Fock states, coherent states, squeezed states
4. Distribution functions in quantum optics, homodyne
5. Coherence and 2nd order correlation functions, Hanbury-Brown and Twiss
6. Quantum entanglement and Bell inequalities
7. Parametric down-conversion and entangled photons
8. Brief overview of applications of quantum entanglement: Quantum Key Distribution and Quantum Computing.
9. Light-Matter interactions: Jaynes-Cummings model, Mollow spectrum, Dressed States
10. Cavity-QED in the Strong Coupling and Fast Cavity Regimes, photon-atom gates
11. Brief overview of open quantum systems and cascaded systems formalism

Learning Outcomes

1. Use the fundamental concepts and analytic description of quantized light – from classical light (coherent states) to non classical light such as single photons, entangled photons and squeezed vacuum. Understand and be able to use the concepts of coherence, 2nd order coherence, and multi-photon interference.
2. Understand and be able to quantify entangled states of light and matter, and be familiar the most common non-classicality tests such as anti-bunching, Bell inequality, etc.
3. Demonstrate familiarity with the fundamental concepts and analytic description of light-matter interactions.
