Content, Learning Outcome and Preconditions

Content

Despite the fact that sometimes superconductivity is still considered exotic, superconductivity meanwhile has a   number of important applications. In this special course the most relevant present and future applications of superconductivity are discussed, starting from what is commonly referred to as the macroscopic quantum  model of superconductivity. The application of superconducting circuits for the realization of future quantum electronics has attracted strong interest, in particular regarding the implementation of quantum information processing systems. They are intensively studied in various collaborative research projects (e.g. SFB 631, cluster of excellence NIM). In this module we address the physics of superconducting quantum circuits and show how such circuits can be implemented based on superconducting thin films and nanostructures. We also discuss the application of superconducting quantum circuits in the study of fundamental light-matter interaction, the realization of solid state based quantum information processing systems and in quantum simulation.

Regarding the application of superconductivity in electronics and for sensors the course addresses the following topics:  

  • macroscopic quantum model of superconductivity
  • Josephson effects
  • Josephson junctions and Superconducting Quantum Interference Devices (SQUIDs)
  • Josephson voltage standard
  • superconducting digital electronics
  • superconducting particle detectors & microwave applications
  • solid-state based quantum information processing devices

Regarding the application of superconductivity in quantum electronics, the following specific topics will be addressed:

  • introduction to secondary quantumn effects
  • superconducting quantum circuits: from resonators to qubits
  • circuit Quantum electrodynamics: "Quantum octics on a chip"
  • quantum information processing with superconducting circuits
  • propagating quantum microwaves

Learning Outcome

By the participation in this module the students acquire profound knowledge on superconducting electronics, superconducting sensors, as well as on superconducting quantum electronics and quantum circuits. This allows them to understand, to analyze and to evaluate specific problems to the following aspects: 
1) macroscopic quantum model of superconductivity, 2) Josephson effects, 3) Josephson junctions and Superconducting Quantum Interference Devices (SQUIDs), 4) Josephson voltage standard, 5) superconducting digital electronics, 6) superconducting particle detectors & microwave applications, 7) secondary quantumn effects, 8) superconducting quantum circuits: from resonators to qubits, 9) circuit Quantum electrodynamics: "Quantum octics on a chip", 10) quantum information processing with superconducting circuits, 11) propagating quantum microwaves.

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 90 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?

Biophysics

Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
