Schmidt number criterion via general symmetric informationally complete measurements
Zhen Wang, Bao-Zhi Sun, Shao-Ming Fei +1
The Schmidt number characterizes the quantum entanglement of a bipartite mixed state and plays a significant role in certifying entanglement of quantum states. We derive a Schmidt…
Separability criteria based on realignment
Yu Lu, Zhong-Xi Shen, Shao-Ming Fei +1
The detection of entanglement in a bipartite state is a crucial issue in quantum information science. Based on realignment of density matrices and the vectorization of the reduced…
Unified monogamy relations for the generalized -class states beyond qubits
Zhong-Xi Shen, Wen Zhou, Dong-Ping Xuan +2
The monogamy of entanglement stands as an indispensable feature within multipartite quantum systems. We study monogamy relations with respect to any partitions for the generalized…
Quantum partial coherence measures constructed from Fisher information
Dong-Ping Xuan, Zhong-Xi Shen, Wen Zhou +3
Quantum mechanics gives a new breakthrough to the field of parameter estimation. In the realm of quantum metrology, the precision of parameter estimation is limited by the quantum…
Coherence and entropy complementarity relations of generalized wave-particle duality
Kang-Kang Yang, Zhi-Xi Wang, Shao-Ming Fei
The concept of wave-particle duality holds significant importance in the field of quantum mechanics, as it elucidates the dual nature encompassing both wave-like and particle-like…
Tighter superadditivity relations for -norm coherence measure
Kang-Kang Yang, Zhong-Xi Shen, Zhi-Xi Wang +1
Quantum coherence serves as a crucial physical resource, with its quantification emerging as a focal point in contemporary research. Superadditivity constitutes one of the most fun…
