Resource-efficient quantum approximate optimization algorithm via Bayesian optimization and maximum-probability evaluation
Siran Zhang, Shuming Cheng
The quantum approximate optimization algorithm (QAOA) is a leading variational approach to combinatorial optimization, but its practical performance depends strongly on objective d…
Optimization landscapes of variational quantum algorithms
Xiaozhen Ge, Shuming Cheng, Guofeng Zhang +1
Optimization plays a central role in variational quantum algorithms, where the objective function typically takes the form $F(\boldsymbolθ)= \sum_{m=1}^{M} f_m \left(\mathrm{Tr}[U(…
Experimental verification of the steering ellipsoid zoo via two-qubit states
Kai Xu, Lijun Liu, Ning-Ning Wang +6
Quantum steering ellipsoid visualizes the set of all qubit states that can be steered by measuring on another correlated qubit in the Bloch picture. Together with local reduced sta…
Tripartite entanglement measure under local operations and classical communication
Xiaozhen Ge, Lijun Liu, Shuming Cheng
Multipartite entanglement is an indispensable resource in quantum communication and computation, however, it is a challenging task to faithfully quantify this global property of mu…
Quantum Steering: Practical Challenges and Perspectives
Yu Xiang, Shuming Cheng, Qihuang Gong +2
Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the "spooky-action-at-a-distance" that one party is able to remotely alter the states of the other if they shar…
Experimentally ruling out joint reality based on operational completeness
Qiuxin Zhang, Yu Xiang, Xiaoting Gao +9
Whether the observables of a physical system admit real values is of fundamental importance to a deep understanding of nature. In this work, we report a device-independent experime…
Quantized Primal-Dual Algorithms for Network Optimization with Linear Convergence
Ziqin Chen, Shu Liang, Li Li +1
This paper studies the network optimization problem about which a group of agents cooperates to minimize a global function under practical constraints of finite bandwidth communica…
Generalising the Horodecki criterion to nonprojective qubit measurements
Michael J. W. Hall, Shuming Cheng
The Horodecki criterion provides a necessary and sufficient condition for a two-qubit state to be able to manifest Bell nonlocality via violation of the Clauser-Horne-Shimony-Holt…
Recycling qubits for the generation of Bell nonlocality between independent sequential observers
Shuming Cheng, Lijun Liu, Travis J. Baker +1
There is currently much interest in the recycling of entangled systems, for use in quantum information protocols by sequential observers. In this work, we study the sequential gene…
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…
Limitations on sharing Bell nonlocality between sequential pairs of observers
Shuming Cheng, Lijun Liu, Travis J. Baker +1
We give strong analytic and numerical evidence that, under mild measurement assumptions, two qubits cannot both be recycled to generate Bell nonlocality between multiple independen…
Device-independent verification of Einstein-Podolsky-Rosen steering
Yuan-Yuan Zhao, Chao Zhang, Shuming Cheng +10
Entanglement lies at the heart of quantum mechanics, and has been identified an essential resource for diverse applications in quantum information. If entanglement could be verifie…
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…

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…
Monogamy relations for nonclassical correlations of multi-qubit states
Shuming Cheng, Lijun Liu
Nonclassical correlations have been found useful in many quantum information processing tasks, and various measures have been proposed to quantify these correlations. In this work,…
Anisotropic invariance and the distribution of quantum correlations
Shuming Cheng, Michael J. W. Hall
We report the discovery of two new invariants for three-qubit states which, similarly to the 3-tangle, are invariant under local unitary transformations and permutations of the par…
Volume monogamy of quantum steering ellipsoids for multi-qubit systems
Shuming Cheng, Antony Milne, Michael J. W. Hall +1
The quantum steering ellipsoid can be used to visualise two-qubit states, and thus provides a generalisation of the Bloch picture for the single qubit. Recently, a monogamy relatio…
Complementarity relations for quantum coherence
Shuming Cheng, Michael J. W. Hall
Various measures have been suggested recently for quantifying the coherence of a quantum state with respect to a given basis. We first use two of these, the l_1-norm and relative e…
