Secure Key from Quantum Discord
Rong Wang, Guan-Jie Fan-Yuan, Zhen-Qiang Yin +6
The study of quantum information processing seeks to characterize the resources that enable quantum information processing to perform tasks that are unfeasible or inefficient for c…
Quantum Discord Witness With Uncharacterized Devices
Rong Wang, Yao Yao, Zhen-Qiang Yin
Quantum discord represents a correlation beyond classicality that could be useful for many quantum information tasks, and therefore is viewed as a valuable quantum resource. Theore…
Scattering-lens based quantum imaging beyond shot noise
Dong Li, Yao Yao
The scheme of optical imaging using scattering lens can provide a resolution beyond the classical optical diffraction limit with a coherent-state input. Nevertheless, due to the sh…
Excess-noise suppression for a squeezed state propagating through random amplifying media via wave-front shaping
Dong Li, Song Sun, Yao Yao
After propagating through a random amplifying medium, a squeezed state commonly shows excess noise above the shot-noise level. Since large noise can significantly reduce the signal…

Yao Yao, Dong Li, C. P. Sun
As an analogy of best separable approximation (BSA) in the framework of entanglement theory, here we concentrate on the notion of best incoherent approximation, with application to…

Dong Li, Chun-hua Yuan, Yao Yao +3
We theoretically study the effects of loss on the phase sensitivity of an SU(1,1) interferometer with parity detection with various input states. We show that although the sensitiv…
Comment on "Unified view of quantum correlations and quantum coherence"
Yao Yao, Li Ge, Mo Li
We show that contrary to what it is claimed in Phys. Rev. A \textbf{94}, 022329 (2016), in general the local projective measurement that induces maximal coherence loss is \textit{n…
Interpreting quantum coherence through a quantum measurement process
Yao Yao, G. H. Dong, Xing Xiao +2
Recently, there has been a renewed interest in the quantification of coherence or other coherence-like concepts within the framework of quantum resource theory. However, rigorously…
Enhanced quantum teleportation in the background of Schwarzschild spacetime by weak measurements
Xing Xiao, Yao Yao, Yan-Ling Li +1
It is commonly believed that the fidelity of quantum teleportation in the gravitational field would be degraded due to the heat up by the Hawking radiation. In this paper, we point…
Retrieving the lost fermionic entanglement by partial measurement in noninertial frames
Xing Xiao, Ying-Mao Xie, Yao Yao +2
The initial entanglement shared between inertial and accelerated observers degrades due to the influence of the Unruh effect. Here, we show that the Unruh effect can be completely…
Maximal coherence in generic basis

Since quantum coherence is an undoubted characteristic trait of quantum physics, the quantification and application of quantum coherence has been one of the long-standing central t…
