Performance advantage of discriminating one-versus-two incoherent sources based on quantum hypothesis testing
Jian-Dong Zhang, Mei-Ming Zhang, Chuang Li +1
Detecting the presence of multiple incoherent sources is a fundamental and challenging task for quantum imaging, especially within sub-Rayleigh region. In this paper, the discrimin…
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…
Phase sensitivity approaching quantum Cramer-Rao bound in a modified SU(1,1) interferometer
Jian-Dong Zhang, Chenglong You, Chuang Li +1
SU(1,1) interferometers, based on the usage of nonlinear elements, are superior to passive interferometers in phase sensitivity. However, the SU(1,1) interferometer cannot make ful…
