Quantum-enhanced SU(1,1) interferometry via a Fock state
Shuai Wang, Jian-Dong Zhang, Xue-Xiang Xu
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-averagi…

SU(1,1) interferometry with parity measurement
Shuai Wang, Jiandong Zhang
We present a new operator method in the Heisenberg representation to obtain the signal of parity measurement within a lossless SU(1,1) interferometer. Based on this method, it is c…
