Subject fundamentals
Aim of this course is to develop and analyze some features of coherent waves (mostly electromagnetic) using a simple language and focusing on specific aspects of coherence with specific interest in applications. The course will deal with lasers, holography, interference and diffraction of coherent waves, and some modern applications of quantum mechanics, such as quantum cryptography and teleportation. A heuristic approach will be used; the course can be taken by students following different BSc learning programs, preferably but not exclusively in the area of Information Engineering.
Expected learning outcomes
The knowledge transmitted by the course to students involves:

- the working principle of a laser
- the mathematical and physical tools for the treatment of coherence-
- the principles of holography
- the principles of quantum information and cryptography
- the basics of quantum teleportation

The transmitted abilities include:

- designing simple experiments of interference and diffraction of light
- selecting the type of laser most advantageous to a specific industrial application
- designing a simple set of optical devices for taking static holograms
Prerequisites / Assumed knowledge
The students must know the subjects of elementary Physics (mechanics, thermodynamics, electromagnetism), basic Mathematics (Calculus I, Calculus II, Geometry) and chemistry (atomic and molecular levels, transitions).

The abilities a student must have include: applying the laws of classical electromagnetism; applying differential and integral calculus in one and more than one dimensions; applying the basic concepts of linear algebra (matrices; vectors; linear operators)
Contents
1) Meaning of a wave: recollection from basic physics. Wave generation: examples of elementary sources. Elementary description of wave coherence (1 ECTS)
2) Coherent electromagnetic wave generation: physical principles of the laser, types of lasers. Features and applications of coherent radiation from a laser (1,5 ECTS).
3) Interference of coherent light (0,5 ECTS)
4) Visibility of interference fringes and quantitative treatment of wave coherence. Spatial and temporal coherence. Measurement of the coherence of a wave; techniques for the measurement of partial coherence (1 ECTS)
5) Holography and holograms (0,5 ECTS)
6) Classical interferometers: Michelsonís and Fabry-Perotís (0,5 ECTS)
7) Quantum interferometry of photons: application to the modern techniques of information treatment and quantum cryptography (0,5 ECTS)
6) Entangled states of quantum particles. Application to quantum teleportation (0,5 ECTS)
Delivery modes
Simple numerical examples of the subjects treated in the course will be solved in practice classes involving all students

Assessment and grading criteria
The exam is a written test followed by a non-compulsory oral test. The written test has a max. duration of 1,5 hrs and consists of a first part with questions with multiple answers and sentences whose validity is to assess or disprove (in this part the students can use supporting material in printed form); followed by a second part where students must answer in writing to a general question pertinent to the program (in this part the students cannot use any supporting material). If the student does not ask for the oral test, the score of the written test gives the final mark. If the student asks for the oral test instead, the final mark is a weighted average between the scores of the written and oral parts.
