Quantum uncertainty relation using coherence
Xiao Yuan, Ge Bai, Tianyi Peng +1
Measurement outcomes of a quantum state can be genuinely random (unpredictable) according to the basic laws of quantum mechanics. The Heisenberg-Robertson uncertainty relation puts…
Simulating single photons with realistic photon sources
Xiao Yuan, Zhen Zhang, Norbert Lutkenhaus +1
Quantum information processing provides remarkable advantages over its classical counterpart. Quantum optical systems are proved to be sufficient for realizing general quantum task…
Observation of Ten-photon Entanglement Using Thin BiBO Crystals
Luo-Kan Chen, Zheng-Da Li, Xing-Can Yao +13
We report on the experimental realization of a ten-photon Greenberger-Horne-Zeilinger state using thin BiBO crystals. The observed fidelity is , demonstr…
Efficient measurement-device-independent detection of multipartite entanglement structure
Qi Zhao, Xiao Yuan, Xiongfeng Ma
Witnessing entanglement is crucial in quantum information processing. With properly preparing ancillary states, it has been shown previously that genuine entanglement can be witnes…
Experimental Quantum Randomness Processing
Xiao Yuan, Ke Liu, Yuan Xu +7
Coherently manipulating multipartite quantum correlations leads to remarkable advantages in quantum information processing. A fundamental question is whether such quantum advantage…
Quantum Coherence and Intrinsic Randomness
Xiao Yuan, Qi Zhao, Davide Girolami +1
The peculiar uncertainty or randomness of quantum measurements stems from coherence, whose information-theoretic characterization is currently under investigation. Under the resour…
