Metrological usefulness of entanglement and nonlinear Hamiltonians
The authors establish metrological criteria for entanglement in quantum systems with nonlinear Hamiltonians, deriving separability bounds for quantum Fisher information. Their findings reveal classes of entangled states beyond GHZ-like structures, offering insights into the metrological advantages of nonlinear dynamics.
