A Double-Threshold Technique for Fast Time-Correspondence Imaging
Ming-Fei Li, Yu-Ran Zhang, Xue-Feng Liu +4
We present a robust imaging method based on time-correspondence imaging and normalized ghost imaging (GI) that sets two thresholds to select the reference frame exposures for image…
Quantum Metrology via Repeated Quantum Nondemolition Measurements in "Photon Box"
Yu-Ran Zhang, Jie-Dong Yue, Heng Fan
In quantum metrology schemes, one generally needs to prepare copies of entangled particles, such as entangled photon states, and then they are detected in a destructive pro…
Quantum-enhanced metrology for multiple phase estimation with noise
Jie-Dong Yue, Yu-Ran Zhang, Heng Fan
We present a general framework to study the simultaneous estimation of multiple phases in the presence of noise as a discretized model for phase imaging. This approach can lead to…
General monogamy property of global quantum discord and the application
Si-Yuan Liu, Yu-Ran Zhang, Li-Ming Zhao +2
We provide a family of general monogamy inequalities for global quantum discord (GQD), which can be considered as an extension of the usual discord monogamy inequality. It can be s…
Zeno dynamics in quantum open systems
Yu-Ran Zhang, Heng Fan
Quantum Zeno effect shows that frequent observations can slow down or even stop the unitary time evolution of an unstable quantum system. This effect can also be regarded as a phys…
Criterion on remote clocks synchronization within a Heisenberg scaling accuracy
Yong-Liang Zhang, Yu-Ran Zhang, Liang-Zhu Mu +1
We propose a quantum method to judge whether two spatially separated clocks have been synchronized within a specific accuracy . If the measurement result of the experiment is ob…
Time-correspondence differential ghost imaging
Ming-Fei Li, Yu-Ran Zhang, Kai-Hong Luo +2
Experimental data with digital masks and a theoretical analysis are presented for an imaging scheme that we call time-correspondence differential ghost imaging (TCDGI). It is shown…
