Lecture

Quantum Metrology: Spin-Squeezing and Interferometry

Description

This lecture covers the concept of spin-squeezing in quantum metrology, exploring the generation methods and applications of spin-squeezed states in interferometry beyond the standard quantum limit. The instructor discusses the experimental setups using Bose-Einstein condensates and atom chips, as well as the detection techniques and phase estimation involved in achieving spin noise reduction and entanglement. Various experiments and results are presented, showcasing the potential of spin-squeezed states for enhancing precision measurements in fields such as field and force sensing. The lecture also delves into quantum Fisher information and the Heisenberg limit in the context of phase estimation.
