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…
Generalized product-form monogamy relations in multi-qubit systems
Wen Zhou, Zhong-Xi Shen, Hong-Xing Wu +2
Monogamy of entanglement essentially characterizes the entanglement distributions among the subsystems. Generally it is given by summation-form monogamy inequalities. In this paper…
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…
Mutually unbiased measurements-induced lower bounds of concurrence
Yu Lu, Meng Su, Zhong-Xi Shen +3
We propose a family of lower bounds for concurrence in quantum systems using mutually unbiased measurements, which prove more effective in entanglement estimation compared to exist…
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 t…
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 (…
