Description

This lecture introduces the concepts of quantum sensing and metrology, focusing on the limitations imposed by quantum mechanics on measurement precision. It covers a unified geometric framework for analyzing metrology with elementary quantum systems, including magnetic moments in magnetic fields, two-level systems under AC drive, and interferometry with entangled photons. The instructor discusses the sensitivity of measurements and the use of elementary quantum systems for non-invasive sensing. The lecture also explores the application of resonant drives and the rotation of coordinates in magnetic resonance problems. Additionally, it delves into the similarities between using photons, spins, and atoms as sensors.
