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…

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…
