Web9 May 2024 · In this paper, we derive a general expression of the quantum Fisher information of an SU(1,1) interferometer with an arbitrary state and a Fock state as inputs by the phase-averaging method. Our results show that the same quantum Fisher information can be obtained regardless of the specific form of the arbitrary state. Then, we analytically … Web2 Aug 2024 · We address SU (1,1) interferometry in the presence of phase diffusion and photon losses and evaluate analytically the corresponding quantum Fisher information. …
