Prerequisites
The course is largely self-contained, although prior knowledge of Communication Theory, Electromagnetic Theory, basic linear algebra, and probability is recommended.
Objectives
By the end of the course, students will be able to:
- Describe the fundamental principles of quantum mechanics and quantum information relevant to communications.
- Analyze quantum resources and protocols for secure communications.
- Compare quantum and post-quantum cryptographic approaches.
- Evaluate the main technological limitations of terrestrial and space quantum communication systems.
- Analyze the performance and security trade-offs of quantum and post-quantum communication protocols.
Learning outcomes
- (CA29) Integrate hybrid cryptosystems (combining classical, quantum, and post-quantum cryptography) into complex telecommunications networks, ensuring continuity of services, smooth transition to quantum-resilient systems, and their energy efficiency.
- (KA28) Define the fundamental principles of quantum cryptography, the threats posed by quantum computers to classical cryptographic systems, and the solutions proposed by post-quantum cryptographic algorithms.
- (KA29) Recognise protocols based on quantum physics and post-quantum algorithms, evaluating their advantages and limitations for their implementation in telecommunications networks.
- (SA40) Design telecommunications networks that incorporate advanced security solutions based on quantum and post-quantum cryptography, ensuring data protection and user privacy.
- (SA41) Analyse potential quantum threats, appropriate cryptographic algorithms, and mitigation strategies to ensure security and privacy in telecommunications networks.

The teaching methodology for this course will consist of:
- Weekly two-hour sessions focused on conceptual content.
- Five practical learning sessions based on projects and experiments.
The practical learning sessions will be compulsory and must be attended in person.
The UAB Virtual Campus (https://cv.uab.cat/) will be used as the platform for communication and teaching support.
The use of artificial intelligence tools will be permitted and recommended as a learning aid. However, teaching staff may, at random, ask individual oral questions without access to AI tools in order to verify students’ understanding and authorship of the work carried out.
For the practical learning sessions, students will work with the equipment available in the Quantum Laboratory and with the simulation and analysis tools indicated by the teaching staff.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Assignments and activities proposed during the conceptual sessions | 33 | 12 | 0.48 | KA28, SA41 |
| Final exam | 33 | 3 | 0.12 | CA29, KA28, KA29, SA40, SA41 |
| Reports corresponding to the practical sessions | 34 | 12 | 0.48 | CA29, KA28, KA29, SA40, SA41 |
ASSESSMENT
Assessment in this course will be continuous and will consist of three activities:
- A. Comprehension questionnaire on the conceptual content — 33%
- B. Assignments and activities proposed during the conceptual sessions — 33%
- C. Reports corresponding to the practical sessions — 34%
The final grade will be calculated using the weighted average above, provided that the grade obtained in each of the three activities is at least 3.0 out of 10. If any activity receives a grade below 3.0, the weighted average will not be applied and the course cannot be passed by compensation with the other activities.
Assessment activities corresponding to component A will be individual. Activities corresponding to components B and C may be carried out in groups when indicated.
Late submissions
Submissions made after the deadline will incur a penalty of 20% of the grade for each day of delay.
Resit assessment
Students who have participated in at least two thirds of the assessment activities may be eligible for the resit process, provided that they have obtained a minimum final grade of 3.5.
The resit process will consist of:
- an additional test or questionnaire for component A;
- a new submission deadline for recoverable activities corresponding to component B and/or C.
No differentiated treatment is envisaged for students repeating the course.
Not assessable
The final grade will be recorded as “Not assessable” only when the student has not participated in the assessment process under the terms established by the current academic regulations.
Honours
An Honours distinction may be awarded to students who obtain a final grade of 9.0 or higher, also taking into account their active participation and overall performance in the course, within the limits established by current regulations.
ACADEMIC INTEGRITY
1. Academic irregularities
Without prejudice to any other disciplinary measures that may apply, and in accordance with the current academic regulations, any irregularity that may alter the grade of an assessed activity may result in a grade of 0 for that activity.
Activities graded in this way will not be recoverable.
Academic irregularities include, among others:
- copying all or part of a practical assignment, report or other assessed activity;
- allowing another student to copy;
- submitting as one’s own work carried out wholly or partly by persons outside the group;
- presenting third-party materials as one’s own without appropriate attribution;
- using unauthorized resources, documentation, devices or tools during an individual assessment;
- communicating with other students during an individual assessment when this is not permitted;
- copying or attempting to copy during an assessment.
2. Use of artificial intelligence tools
The use of artificial intelligence tools will be subject to the conditions established for each activity.
When their use is permitted, students remain responsible for the authorship, accuracy, quality and justification of the work submitted, and must be able to explain and defend their results orally when requested by the teaching staff.
3. Oral verification
Teaching staff may carry out random individual oral verifications of submitted activities.
Students must demonstrate a sufficient level of understanding and an ability to justify the work submitted. If the verification is considered insufficient, the grade for the corresponding activity will be reduced by 50%.
4. Academic consequences
In the event of academic irregularities, the final grade will be limited in accordance with the current academic regulations, and the course cannot be passed by compensation.
In summary, copying, allowing others to copy, plagiarizing or using unauthorized resources in an assessed activity may result in failure of that activity and, where applicable, failure of the course.
