Syllabus
Prerequisites: Digital communications: principles and analysis of a digital link in terms of error probability.
Vector spaces.
Probability and theory of random processes.
Target skills and knowledge: Optical communications
The overall objective is to analyze the performance and get the capability of designing the link in classical optical fibre communications.
In detail the knowledge to be acquired is:
- the structure of the optical fibre and its parameters
- the optical sources: laser and LED
- the model of the optical link and its components
- the digital signal in the link and their characteristics
- the source of noises, in particular the shot noise
- the photon counting statistics, with photo-detectors and optical amplifiers
- evaluation of the error probability
- principles of coherent optical communications
In terms of skills, the objectives are:
- Characterize the optical fibre and its main parameters and their impact on the communication system.
- Analyze the performance of a fibre communication system according to all the noise sources
- Characterize the shot noise and the excess noise in photo-detectors and optical amplifiers.
- Analyze the optical link and evaluate the error probability
- Design the optical link
- Analyze the performance (error probability) of coherent systems

Quantum communications
The overall objective is to understand the principles of quantum communications systems, in particular with coherent states.
In detail the knowledge to be acquired is:
- Dirac's notation and the mathematics of Hilbert spaces: operators, spectral decomposition, projectors
- The postulates of quantum mechanics
- The theory of quantum measurements
- The model and the analysis tools of a quantum communications system
- The theory for the evaluation and the optimization od the error probability.
- Coherent states
- Evaluate the error probability of quantum communication systems with coherent states.
The skills to be acquired are:
- Acquire the use of the basic mathematical tools to operate on Hilbert spaces: operators, spectral decomposition, projectors
- Acquire the principles of quantum mechanics related to the theory of quantum measurements
- Acquire the capability to model a quantum communication system
- Characterize the quantum communication system in terms of error probability.
- Characterize coherent quantum states
- Use the mathematical tools of quantum measurements to compare the performance of classical and quantum communication systems with coherent states
Examination methods: Written exam at the end of the course
Assessment criteria: The evaluation will be based on the solution of exercises that assess the capacity of designing and analysis, with a weight of about 60% for classical optical communications and about 40% to asses the knowledge of the mathematical tools for the analysis of quantum communications.
