Detecting quantum entanglement with unsupervised learning
Yiwei Chen, Yu Pan, Guofeng Zhang +1
Quantum properties, such as entanglement and coherence, are indispensable resources in various quantum information processing tasks. However, there still lacks an efficient and sca…
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…
Experimental Verification of Anisotropic Invariance for Three-Qubit States
Jie Zhu, Meng-Jun Hu, Shuming Cheng +4
We experimentally test the recently predicted anisotropic invariance properties of pure three-qubit states, via generation and measurement of polarisation-path entangled three-qubi…
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…
