Fundamentals of quantum sensing and metrology

QUANT-412 / 5 credits

Teacher: Javerzac-Galy Clément Christian

Language: English

Summary

This course introduces the physical principles and technologies behind quantum measurement systems. Emphasis is placed on both theoretical foundations and real-world implementations.

Content

  • Quantum noise and noise analysis.
  • Standard quantum limits.
  • Quantum measurements.
  • Measurement and quantum back-action.
  • Quantum nondemolition and evading quantum limits.
  • Measurements with photons.
  • Quantum sensing schemes.
  • Cutting-edge sensors using e.g. atoms, spins, or photons.
  • Applications in magnetometry, timekeeping, gravimetry, gravitational waves detection, metrology and beyond.
  • Advantages of quantum resources over classical approaches.
