Diploma(s)
Spring semester
Level Master 2 3 ECTS - English
Contact - Secrétariat de l’enseignement

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 (JaynesCummings model, resonant and dispersive interaction, Schrödinger cat states of light) and then moves to the more recent developments of circuit QED. 

Syllabus

The body of lectures will consists of two parts :

  1. Cavity QED : description of the interaction between a single atom and the mode of the field, Jaynes-Cummings model, Rabi oscillation, dispersive interaction, generation of Schrödinger cat states, QND measurement of the field, decoherence).
  2. Circuit QED : implementing CQED concepts in superconducting circuits. 
Prerequisites

Basic knowledge on Quantum Mechanics and Light/Field interaction

Evaluation

We will organize an exam (written or oral) at the end of the semester.
