Simultaneous Detection of High-Dimensional Entanglement for Two Unknown Quantum States
Mao-Sheng Li, Chang-Yue Zhang, Zheng Zheng +7
The state overlap, quantified via $\tr[ÏÏ]$, is a metric widely used to assess the closeness between two quantum states and . Although global state overlap alone does no…
Quantum-Enhanced Sensing Enabled by Scrambling-Induced Genuine Multipartite Entanglement
Guantian Hu, Wenxuan Zhang, Zhihua Chen +16
Quantum sensing leverages quantum resources to surpass the standard quantum limit, yet many existing protocols rely on the preparation of complex entangled states and Hamiltonian e…
Machine learning-aided direct estimation of coherence and entanglement for unknown states
Ting Lin, Zhihua Chen, Kai Wu +3
Quantum coherence and entanglement are fundamental resources in quantum technologies, yet their efficient estimation for unknown states by employing minimal resources in experiment…
Decoding Quantum Search Advantage: The Critical Role of State Properties in Random Walks
Si-Qi Zhou, Jin-Min Liang, Ziheng Ding +3
Quantum algorithms have demonstrated provable speedups over classical counterparts, yet establishing a comprehensive theoretical framework to understand the quantum advantage remai…
Static and dynamic coherence fraction in the Bernstein-Vazirani algorithm
Si-Qi Zhou, Jin-Min Liang, Jiayin Peng +3
Quantum entanglement and coherence are crucial resources in quantum information theory. In some scenarios, however, it is not necessary to directly estimate entanglement or coheren…
Quantifying Quantum Steering with Limited Resources: A Semi-supervised Machine Learning Approach
Yansa Lu, Zhihua Chen, Zhihao Ma +1
Quantum steering, an intermediate quantum correlation lying between entanglement and nonlocality, has emerged as a critical quantum resource for a variety of quantum information pr…
