In this module the master students will participate in real lab experiments at several partner schools.

A case study is a lecture on three hours only aiming is to tell the complete “story” of a quantum device or a quantum effect from the discovery or realisation to today’s impact on the scientific community and even to society. The challenge is to be exhaustive within the time limit, i.e. to give the theoretical basis, describe the quantum nature of the effect and explain how it is possible to measure it.

A few examples to give you an idea of what it is about are: Superconducting Quantum Interference Device (SQUID), single-photon detection, a concrete example of light trapping (atoms, dielectric spheres, etc.), the Aharonov-Bohm effect, quantum cascade lasers, ...

The aim is to illustrate a concrete case that demonstrates the quantum effect and makes it visible, bearing in mind that the lecture has to be adapted for the knowledge of M2 students.

The main goal of the course is to study the light-matter interaction at the fundamental level where one two-level system interacts with a single mode of the electromagnetic field. 

The lecture will first presents the fundamental concept of cavity quantum electrodynamics (Jaynes–Cummings model, resonant and dispersive interaction, Schrödinger cat states of light) and then moves to the more recent developments of circuit QED.
