Experimental Measurement-Device-Independent Quantum Steering and Randomness Generation Beyond Qubits
Yu Guo, Shuming Cheng, Xiaomin Hu +6
In a measurement-device-independent or quantum-refereed protocol, a referee can verify whether two parties share entanglement or Einstein-Podolsky-Rosen (EPR) steering without the…
Entanglement detection by violations of noisy uncertainty relations: A proof of principle
Yuan-Yuan Zhao, Guo-Yong Xiang, Xiao-Min Hu +5
It is well-known that the violation of a local uncertainty relation can be used as an indicator for the presence of entanglement. Unfortunately, the practical use of these non-line…
Distribution of high-dimensional orbital angular momentum entanglement at telecom wavelength over 1km of optical fibre
Huan Cao, She-Cheng Gao, Chao Zhang +11
High-dimensional entanglement has demonstrated potential for increasing channel capacity and resistance to noise in quantum information processing. However, its distribution is a c…
Experimental transmission of quantum information using a superposition of causal orders
Yu Guo, Xiao-Min Hu, Zhi-Bo Hou +7
Communication in a network generally takes place through a sequence of intermediate nodes connected by communication channels. In the standard theory of communication, it is assume…
Experimental validation of quantum steering ellipsoids and tests of volume monogamy relations
Chao Zhang, Shuming Cheng, Li Li +8
The set of all qubit states that can be steered to by measurements on a correlated qubit is predicted to form an ellipsoid---called the quantum steering ellipsoid---in the Bloch ba…
Beating the channel capacity limit for superdense coding with entangled ququarts
Xiao-Min Hu, Yu Guo, Bi-Heng Liu +3
Quantum superdense coding protocols enhance channel capacity by using shared quantum entanglement between two users. The channel capacity can be as high as 2 when one uses entangle…
Experimental Realization of Sequential Weak Measurements of Arbitrary Non-commuting Pauli Observables
Jiang-Shan Chen, Meng-Jun Hu, Xiao-Min Hu +5
Sequential weak measurements of non-commuting observables is not only fundamentally interesting in quantum measurement but also shown potential in various applications. The previou…
Experimental self-testing of entangled states
Wen-Hao Zhang, Geng Chen, Xing-Xiang Peng +12
Quantum entanglement is the key resource for quantum information processing. Device-independent certification of entangled states is a long standing open question, which arouses th…
Measuring Small Longitudinal Phase Shifts via Weak Measurement Amplification
Kai Xu, Xiao-Min Hu, Chao ZHang +6
Weak measurement amplification, which is considered as a very promising scheme in precision measurement, has been applied to various small physical quantities estimation. Since man…
