Learning Outcomes

Upon successful completion of this course students should be able to:

  1. Explain the fundamental concepts of open quantum systems, such as entanglement, measurement theory and system-bath interaction.
  2. Analyze different de-coherence mechanisms in several experimental systems.
  3. Evaluate the Quantumness of several phenomena, such as teleportation, interaction-free measurement and coherent control of quantum thermodynamics.
  4. Formulate their own research topics using concepts and methods learnt.
