Aims of the course

Recently, elusive concepts of quantum mechanics such as superposition and entanglement – which have long been regarded as curiosities of quantum mechanics with no practical purposes – have become the key elements of several technological applications. These fledgling quantum technologies define a new field of physics and engineering, and may  be roughly structured into quantum communication, quantum sensing, quantum simulations, and, last but not least, quantum computing. This lecture will give an overview of the most promising platforms and first applications, following up on a crisp introduction to the basic theoretical concepts needed for their understanding. The course is organized in the framework of the Cluster of Excellence Matter and Light for Quantum Computing (ML4Q). It is aimed at Master students in Physics with a knowledge in quantum mechanics and basic knowledge of condensed matter physics.

Preliminary Schedule

Course prerequisites and required pre-readings

Students who would like to participate in our course should be familiar with the following topics:

  • Quantum mechanics (a must)
  • Statistical Mechanics
  • Basic concepts and mathematical formalism of quantum mechanics (quantum states, evolution, measurements)
  • Basic concepts (light-matter interaction) from quantum optics and laser physics
  • Condensed-matter / solid-state physics
  • Many-body physics
  • Superconductivity
  • The second-quantisation formalism of the BCS theory

The overview of these topics can be found in the pre-readings listed below. We strongly recommend to read them before the course.
