Obiettivi dell'insegnamento

This course provides an introductory overview on the basic principles of quantum optics, their use to understand the fundamental mechanisms of light-matter interaction and the possibility to exploit these concepts to manipulate information in a completely new way as in quantum communication and quantum computation protocols. The course is conceived as a starting point for more specialistic studies and, in general, as a cultural survey over quantum technologies that will be at the basis of the future information society.


Risultati di apprendimento attesi

Attending the lectures and passing the exam will allow the student to:

- Understand the physical basis of quantum optical phenomena;

- Learn the fundamental mechanisms governing light-matter interaction; 

- Learn the principles and the main protocols of quantum information.

 

The student will be able to apply the basic knowledge described above to:

- explain the operating principles of some prototypal optical devices developed for quantum information;

- deepen the understanding of physical phenomena encountered in other courses with a new perspective;

- follow with greater awareness the new trends in the high-tech market (from quantum communications to quantum computing) dealing with quantum technologies.


Argomenti trattati

Quantum optics

  1. Photon Statistics.
  2. Photon bunching and antibunching: Hanbury-Brown and Twiss interferometer.
  3. Quantization of the elecromagnetic field: from Maxwell's equations to quantum operators.
  4. Quantum states of light: Photon number states, coherent light and squeezed light.
  5. Quantum description of an optical beam splitter.
  6. Resonant light – atom interactions: Jaynes-Cummings model, absorption, stimulated and spontaneous emission.
  7. Atoms in optical cavities: dressed states, Rabi oscillations, collapse and revivals.

Quantum Information

  1. Single photon sources.
  2. Quantification of photon indistinguishability by the Hong-Ou-Mandel effect.
  3. Entangled states: generation by spontaneous parametric down conversion.
  4. Einstein-Podolsky-Rosen paradox and Bell’s theorem
  5. Quantum teleportation.
  6. Quantum cryptography: BB84 protocol
  7. Qubits and quantum computing: Deutsch's algorithm, Grover's algorithm, Shor's algorithm

Prerequisiti

No pre-requisites are formally requested. However, a basic understanding of quantum mechanics and his formalism may be useful.


Modalità di valutazione

The exam consists in an oral discussion. The discussion will be based on 2-3 open questions, each on a different topic. The student can chose the topic of the first question.

The aim of the discussion is to ascertain:

- the understanding of the physical basis of quantum optics and information;

- the knowledge of the definitions, theorems and general concepts related to quantum optics and quantum information;

- the capability to discuss, both qualitatively and quantitatively, the quantum physical models and protocols relevant for the course.

 


Bibliografia
Risorsa bibliografica facoltativaChirstopher Gerry and Peter Knight, Introductory quantum optics, Editore: Cambridge University Press, Anno edizione: 2005, ISBN: 978-0-521-52735-4
Note:

This book covers most of the course with a rigorous approach. It requires a good background in quantum mechanics. Sometimes it lacks of physical intuition and thus may be a tough start for those who do not have a solid background.

Risorsa bibliografica facoltativaMark Fox, Quantum optics: an introduction, Editore: Oxford University Press, Anno edizione: 2006, ISBN: 978-0-19-856673-1
Note:

This book is a very good introduction to the field. It is particularly suggested to those who are not too familiar with quantum mechanics. It covers most of the course, although often with a simplified treatment.
