Fisher information susceptibility for multiparameter quantum estimation

2023 · arXiv (Cornell University)

Noise affects the performance of quantum technologies, hence the importance of elaborating operative figures of merit that can capture its impact in exact terms. In quantum metrology, the introduction of the Fisher information measurement noise …

Analysis of spin-squeezing generation in cavity-coupled atomic ensembles with continuous measurements

2024 · Quantum Science and Technology

Abstract We analyze the generation of spin-squeezed states via coupling of three-level atoms to an optical cavity and continuous quantum measurement of the transmitted cavity field in order to monitor the evolution of the atomic …
