The course of Quantum Optics 2 (PHY562) deals with the quantization of the electromagnetic field, the concept of photon, and more generally the interaction processes between matter and quantum light. It goes to the very heart of modern quantum optics, with subjects like squeezed states, single photon states, and entangled pairs of photons, which play an essential role in the new field of quantum information.

List of subjects :

• Quantization of the electromagnetic field, Hamilton formalism, canonical quantization.
  
• The free quantized radiation field : quasi-classical states, squeezed states, single photon states.
  
• Heisenberg’s equations, interferometry with quantum fields.
  
• Interaction between atoms and the quantized radiation field ; spontaneous emission.
  
• Non-linear optics : classical and quantum approaches, twin photon pairs.
  
• Density matrix and Optical Bloch Equations.
  
• Entanglement, Bell’s inequalities, applications to quantum information.
  
• Quantum effects in atom-laser interaction : resonance fluorescence, photon antibunching.
  
• Applications to optoelectronics.
