Measure of set imaginarity
Yu Guo, Jiabo Pan, Yuqin Wang +1
Recent studies have shown that Bargmann invariants provide effective detectors of set imaginarity. In this paper, we investigate set imaginarity as a quantum resource in qubit syst…

Computable lower bound of the parameterized entanglement monotone
Ning Yang, Yu Guo, Shuanping Du
Although numerous measures of entanglement have been proposed so far, the calculation of a given faithful entanglement measure is a hard work since it is always involved in some op…

Unified entropy entanglement
Wenxue Ren, Binghao Li, Ruiqun Niu +2
The unified entropy as a promotion of the von Neumann entropy exhibits distinct diversity which contains the Tsallis entropy, the Rényi entropy, the von Neumann entropy as special…
