Expected competences and skills: • Ability to identify and select the most suited materials and technologies and to apply them for the fabrication of quantum devices. • Ability to apply the acquired knowledge in a research and/or industrial framework, applying capability and skills in solving problems related to the design, simulation, and implementation of quantum devices also in the case of new or unfamiliar issues or into broader and more interdisciplinary application contexts than the pure engineering sector (healthcare, environmental monitoring, food, ...). • Ability to integrate technical knowledge into manufacturing processes. • Ability to communicate in a clear and unambiguous way technical aspects related to the design and manufacture of quantum devices, both in writing and oral form and to both specialists and non-specialists alike. • Independent learning skills that tackle the acquisition and application of know-how related to new techniques, design methodologies and fabrication processes for quantum devices, not necessarily explained and described during the course.

• Physics of technological processes • Quantum mechanics • Basic solid state physics • Quantum condensed matter physics • Elements of chemistry and materials science (acids, bases, polymers, …) • Knowledge of the micro and nano-scale characterization techniques (SEM, TEM, AFM, Raman, XRD, XPS, profilometry, etc.)

Introduction to the course. Elements of quantum optics. Technologies for the realization of single photon sources. Technologies for the realization of quantum sensors. Technologies for photon manipulation. Technologies for the realization of qubits: fabrication and characterization of materials.

The course consists of lectures covering the topics described in the Course Topics section, delivered by slides and the use of the blackboard. The slides will be made available to students in pdf format on the Internet Teaching Portal prior to each lecture.

The lecture material (slides for the lectures) will be distributed in pdf format by the instructors and uploaded on the Teaching Portal prior to each lecture and whenever needed. Some optional additive readings (i.e., scientific literature papers, review papers, manuals, …) will be made available by the teachers on the same abovementioned repository. Suggested but not mandatory additional readings and books will be suggested by the instructors on a need basis.

Expected learning outcomes Understanding of the covered topics and ability to grasp the fundamental aspects of the various technologies and related materials. Ability to compare (advantages/disadvantages) the different technological tools for the manufacture of a device. Ability to compare, identify, and logically use the best technological tools to optimize the manufacturing process of a device. Ability to build a logical path by assembling the various technological processes for the construction of a quantum device. Criteria, rules and procedures for the examination The exam is aimed at ascertaining the knowledge of the topics listed in the official program of the course and the ability to apply the theoretical contents for the solution of simple exercises for the assembly of technological processes. The exam is composed of two parts: 1) a report on a project carried out on a case study assigned by the instructor in class (a seminar of 10 minutes or a essay of max 3000 words); 2) a written exam involving open questions (1 open question, 3 multiple choice questions, 4 true/false questions). Each student will be asked to ascertain their knowledge on the topics studied and their ability to use this knowledge in hypothetical real-life case studies. The total allotted time is 60 minutes. No books, notes or any other didactic material is allowed. The final grade is given by the sum of the score obtained on the project/written report (16/30) and the written exam (16/30). The assessments are expressed in thirtieths and the exam is passed if the mark is at least 18/30. The maximum achievable mark is 30 cum laude. The type of proposed questions aims to test the student ability to understand and revise the topics covered in class lectures, with particular reference to the ability to compare similar technologies, compare results or processing parameters of technological processes or performance of different materials. The main evaluation criteria of the exam consist in the correctness, completeness, and conciseness of the answers to the questions and the correctness of the employed technical language. The exam results are communicated directly to the students at the end of the exam session.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
