Geometric power capacity of coherent ergotropy in quantum batteries
Dong-Ping Xuan, Hua Nan, Zhi-Xi Wang +1
We explore coherent ergotropy extraction in quantum batteries from a resource-geometric point of view. For an initial state , we quantify the coherent extraction process by the…
Quantum Speed Limits Based on the Sharma-Mittal Entropy
Dong-Ping Xuan, Zhi-Xi Wang, Shao-Ming Fei
Quantum speed limits (QSLs) establish intrinsic bounds on the minimum time required for the evolution of quantum systems. We present a class of QSLs formulated in terms of the two-…
A new entanglement measure based on the total concurrence
Dong-Ping Xuan, Zhong-Xi Shen, Wen Zhou +2
Quantum entanglement is a crucial resource in quantum information processing, advancing quantum technologies. The greater the uncertainty in subsystems' pure states, the stronger t…
Quantum-imaginarity-based quantum speed limit
Dong-Ping Xuan, Zhong-Xi Shen, Wen Zhou +2
The quantum speed limit sets a fundamental restriction on the evolution time of quantum systems. We explore the relationship between quantum imaginarity and the quantum speed limit…
Parameterized bipartite entanglement measures and entanglement constraints
Wen Zhou, Zhong-Xi Shen, Dong-Ping Xuan +2
In this paper, we propose a novel class of parameterized entanglement measures which are named as -concurrence (C) (), and demonstrate comprehensively that they…
Monogamy and polygamy for multi-qudit generalized -class states based on concurrence of assistance and Tsallis- entanglement of assistance
Wen Zhou, Zhong-Xi Shen, Dong-Ping Xuan +2
By analyzing the reduced density matrices derived from a generalized -class state under any partition, we present new analytical monogamy inequalities satisfied by the -th ($…
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…
Tighter Constraints of Multi-Qubit Entanglement in Terms of Nonconvex Entanglement Measures LCREN and LCRENoA
Zhong-Xi Shen, Dong-Ping Xuan, Wen Zhou +2
The monogamy property of entanglement is an intriguing feature of multipartite quantum entanglement. Most entanglement measures satisfying the monogamy inequality are turned out to…
