Multiple phase estimation with photon-added multi-mode coherent states of GHZ-type

2025 · International Journal of Modern Physics A

This paper explores multiparameter quantum metrology using Greenberger–Horne–Zeilinger (GHZ)-type photon-added coherent states (PACS) and investigates both independent and simultaneous parameter estimation with linear and nonlinear protocols, highlighting the significant potential of quantum resources to enhance …
