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 Separability Criteria Based on Symmetric Measurements
Yu Lu, Wen Zhou, Meng Su +3
We propose experimentally feasible separability criteria for bipartite systems based on local symmetric measurements. Through detailed examples, we demonstrate that our criteria ca…
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…
Enhanced separability criteria based on symmetric measurements
Yu Lu, Hao-Fan Wang, Meng Su +2
We present separability criteria based on local symmetric measurements. These experimental plausible criteria are shown to be more efficient in detecting entanglement than the curr…
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…
