Even Odd Splitting of the Gaussian Quantum Fisher Information: From Symplectic Geometry to Metrology

Kaustav Chatterjee, Tanmoy Pandit, Varinder Singh +2

We introduce a canonical decomposition of the quantum Fisher information (QFI) for centered multimode Gaussian states into two additive pieces: an even part that captures changes i…
