Multipartite entanglement based on realignment moments
Hui Zhao, Shu-Ying Zhuang, Naihuan Jing +1
Based on the realignment moments of density matrix, we study parameterized entanglement criteria for bipartite and multipartite states. By adjusting the different parameter values,…
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…
Precision bounds for quantum phase estimation using two-mode squeezed Gaussian states
Jian-Dong Zhang, Chuang Li, Lili Hou +1
Quantum phase estimation based on Gaussian states plays a crucial role in many application fields. In this paper, we study the precision bound for the scheme using two-mode squeeze…
Performance advantage of quantum hypothesis testing for partially coherent optical sources
Jian-Dong Zhang, Kexin Zhang, Lili Hou +1
Determining the presence of a potential optical source in the interest region is important for an imaging system and can be achieved by using hypothesis testing. The previous studi…
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…
