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…
Superresolution imaging of two incoherent optical sources with unequal brightnesses
Jian-Dong Zhang, Yiwen Fu, Lili Hou +1
Resolving the separation between two incoherent optical sources with high precision is of great significance for fluorescence imaging and astronomical observations. In this paper,…
Two-parameter estimation with single squeezed-light interferometer via double homodyne detection
Li-li Hou, Jian-Dong Zhang, Kai-Min Zheng +1
The simultaneous two-parameter estimation problem in single squeezed-light Mach-Zehnder interferometer with double-port homodyne detection is investigated in this work. The analyti…
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…
New kind of asymmetric integration projection operators constructed by entangled state representations and parity measurement
S. Wang, Z. P. Wang, J. D. Zhang
By means of the technique of integration within an ordered product of operators and Dirac notation, we introduce a new kind of asymmetric integration projection operators in entang…
