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 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…
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…
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…
