Subject fundamentals
Aim of the course is to develop and study using a simple, not simplistic language some features of coherent waves 8both electromagnetic and quantum) focusing on the outcomes of applicative relevance of coherence of a wave phenomenon. In particular, the course is aimed to describe lasers, holography, and the most modern applications of quantum mechanics, such as quantum information, quantum cryptography, and quantum teleportation. Use will be made of a heuristic approach allowing the lectures to be enjoyed by students belonging in different BSc level courses, not exclusively of the ICT area, thereby guaranteeing a wide audience to the lectures.
Expected learning outcomes
The knowledge acquired by students during the lectures refers to the general paradigms and physical concepts at the basis of numerous applications, either existing or predictable of advanced techniques in fields extending from tridimensional image treatment and representation, including moving images, to mechanical treatments, to precision surgery, to informatics safety and long-distance transfer of quantum information; the abilities to be acquired refer to techniques of analysis of the degree of coherence of any wave phenomenon, the construction techniques of setups for the production of coherent radiation, the techniques at the basis of quantum cryptography based upon coherent photon states, the techniques for the production of entangled quantum states.
Prerequisites / Assumed knowledge
Required knowledge: Basics of Mathematics and Physics (standard mathematical instruments; electromagnetism and waves); Basics of Chemistry (atomic levels and transitions)
Required abilities: solving simple and intermediate problems of Physics using a logical-deductive process; practical use of the instruments of complex calculus and linear algebra.
Contents
1) Definition of wave: an update from elementary Physics. Wave generation: examples of elementary point sources. (1 cr)
2) Coherence of a wave. Space and time coherence. Definition and measurement of the coherence of a wave, techniques for the measurement of partial coherence. (1 ECITS)
3) Production of coherent electromagnetic waves: physical principles of the laser; types of lasers. Properties and applications of the coherent radiation emitted by a laser. Interference and diffraction of laser light, interferometry. (2,5 ECTS)
4) Holography and holograms(0,5 ECTS)
5) Interference and diffraction of quantum particles. Quantum interference of photons: application to the modern techniques of information handling and quantum cryptography (0,5 ECTS)
6) Entangled states of quantum particles. Application to quantum teleportation. (0,5 ECTS)
Delivery modes
Single-squad, in-room numeric exercises refer to the treatment of examples and numerical problems referring to all subjects treated in the lectures. The time devoted to exercises are about one quarter of the total time.
Texts, readings, handouts and other learning resources
Suggested readings for general issues:

G.R. Fowles
Introduction to modern optics
Dover Publications

K. F. Renk
Basics of Laser Physics for Students of Science and Engineering
Springer

For specific subjects:

Gerhard K. Ackermann and Jürgen Eichler
Holography - A Practical Approach
Wiley

and lecture notes/files released by the teacher and made available on the students’ webpage.
Assessment and grading criteria
The final assessment is done through a written exam which can be supplemented by an oral interview. The written exam has a maximum duration of 2 hours and includes a first section where multiple-answer questions and true/false statements must be addressed by the students, who can make use of lecture notes; followed by a second section where the students are asked to write an extended answer to a theme on one of the subjects treated in the course; in this section no support can be used by the students. If a student does not ask for on oral exam, the mark is given by the score of the written exam. in the case of an oral interview, the mark is a weighted average between the score of the written and that of the oral exam.
Notes

The course is given in Italian. The teacher is Dr. Paolo Allia, DISAT. No threshold to the number of students (below 150) is required.
