Tight upper bound of the maximal quantum violation of Gisin's elegant Bell inequality and its application in randomness certification
Dan-Dan Hu, Meng-Yan Li, Fen-Zhuo Guo +3
The violation of a Bell inequality implies the existence of nonlocality, making device-independent randomness certification possible. This paper derives a tight upper bound for the…
Quantifying the intrinsic randomness in sequential measurements
Xinjian Liu, Yukun Wang, Yunguang Han +1
In the standard Bell scenario, when making a local projective measurement on each system component, the amount of randomness generated is restricted. However, this limitation can b…
Self-testing of different entanglement resources via fixed measurement settings
Xinhui Li, Yukun Wang, Yunguang Han +1
Self-testing, which refers to device independent characterization of the state and the measurement, enables the security of quantum information processing task certified independen…
Robust one-sided self-testing of two-qubit states via quantum steering
Yukun Wang, Xinjian Liu, Shaoxuan Wang +2
Entangled two-qubit states are the core building blocks for constructing quantum communication networks. Their accurate verification is crucial to the functioning of the networks,…
Optimal Verification of the Bell State and Greenberger-Horne-Zeilinger States in Untrusted Quantum Networks
Yun-Guang Han, Zihao Li, Yukun Wang +1
Bipartite and multipartite entangled states are basic ingredients for constructing quantum networks and their accurate verification is crucial to the functioning of the networks, e…
Estimation on geometric measure of quantum coherence
Hai-Jun Zhang, Bin Chen, Ming Li +2
We study the geometric measure of quantum coherence recently proposed in [Phys. Rev. Lett. 115, 020403 (2015)]. Both lower and upper bounds of this measure are provided. These boun…
