Harnessing Non-convex Quantum Correlations of Independent Qubits
Liang-Liang Sun, Xiang Zhou, Chengjie Zhang +3
Quantum correlations in Bell and prepare-and-measure experiments are central resources for probing nonclassicality and enabling device-based quantum information protocols. In the a…
Variational Optimization for Quantum Problems using Deep Generative Networks
Lingxia Zhang, Xiaodie Lin, Peidong Wang +4
Optimization drives advances in quantum science and machine learning, yet most generative models aim to mimic data rather than to discover optimal answers to challenging problems.…
Cost of Locally Approximating High-Dimensional Ground States of Contextual Quantum Models
Kaiyan Yang, Yanzheng Zhu, Xiao Zeng +3
Contextuality, one of the strongest forms of quantum correlations, delineates the quantum world and the classical one. It has been shown recently that some quantum models, in the f…
Causality and Duality in Multipartite Generalized Probabilistic Theories
Yiying Chen, Peidong Wang, Zizhu Wang
Causality is one of the most fundamental notions in physics. Generalized probabilistic theories (GPTs) and the process matrix framework incorporate it in different forms. However,…
MindSpore Quantum: A User-Friendly, High-Performance, and AI-Compatible Quantum Computing Framework
Xusheng Xu, Jiangyu Cui, Zidong Cui +36
We introduce MindSpore Quantum, a pioneering hybrid quantum-classical framework with a primary focus on the design and implementation of noisy intermediate-scale quantum (NISQ) alg…
