Other contents


Gender inclusive considerations

The gender perspective will be incorporated in the development of the subject, as far as possible.

Attention to diversity will be considered by developping different teaching methods (lecture, lab work, autonomous learning, team work, etc), by promoting inclusive participation and by using a variety of evaluation tools that enhance different skills.

Independent learning






  1. The course assumes basic concepts of electronics and circuit analysis and of computer programming. 

  2. Students are advised to have completed or be enrolled in the subject Quantum Technologies with superconducting circuits.



Competences to be gained during study


  1. Acquire skills to work in a laboratory environment and set-up test benches instrumentation.





Learning objectives


Referring to knowledge

  1. To have an overview of general fundamentals on electronics and its application in quantum technologies. 

  2. To become familiar with methods and techniques to develop laboratory work. 

  3. To become familiar with laboratory instruments and control and acquisition systems. 



Teaching blocks


1. Overview of electronics for physicists


  1. Introduction

  2. Basic electronic components

  3. Basic circuit functionality (filters, amplifiers, active circuits). 

  4. Introduction to lab equipment (including Arduino) and safety 

  5. Transmission lines (impedance matching, reflectometry, etc.).

  6. Noise sources, filtering and signal to noise ratio. 

  7. Electromagnetic compatibility. 

2. Introduction to classical hardware for quantum computing


  1. Introduction

  2. Supplying, controlling and sensing qubits. 

  3. Receiver and transmitter architectures for controlling qubits: frequency up/down-conversion, modulation schemes, frequency generation.

3. Embedded systems for sensing, acquisition and control


  1. Introduction to microcomputers and embedded systems

  2. Introduction to programming of embedded systems

  3. ADCs, DACs and, sampling concepts

  4. Introduction to control (PID)

4. Laboratory practical aspects


  1. Magnetic fields.

  2. Cryogenics.



Teaching methods and general organization


  1. 10 sessions combining theory and lab work

  2. Lectures where theoretical contents of the subject are presented. 

  3. Practical exercise classes in which students may participate. 

  4. Laboratory sessions (teams of 2 people) related to different teaching blocks. A short laboratory report will be produced by each team:

    1. Basic electronics 

    2. Noise and interference

    3. Embedded systems: small project of control and acquisition with Arduino



Official assessment of learning outcomes


  1. Evaluation of laboratory reports and laboratory practical skills (6 points total).

  2. Evaluation of final project with Arduino (4 points).

  3. Members of the teaching staff may also consider students’ participation in class and in the optional tasks they suggest.
