Lecture

Relativistic Quantum Information (260131)

Relativistic Quantum Information (260131) – Lecture 

Professor(s): Ivette Fuentes

Content:

  • An introduction to the basic techniques required to investigate questions in the overlap of quantum mechanics and relativity employing novel tools in quantum information and quantum metrology. Students will learn about the effects of space-time, motion and gravity on quantum properties such as entanglement, and their effects on paradigmatic quantum communication protocols. Applications of quantum metrology to relativistic quantum fields aimed at estimating spacetime parameters will be discussed.
  • Course objectives: To learn techniques in quantum field theory in curved spacetime, quantum information and quantum metrology. To learn how to integrate the techniques mentioned above to study fundamental effects and applications in the overlap of quantum theory and relativity.
