Imaginarity witness
Zhiqi Liang, Yufan Lin, Yu Guo +1
Imaginarity has shown to be an important resource in quantum information. The witness theory of quantum resource, such as entanglement witness, coherence witness, and imaginarity w…
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…
Experimental observation of entropic-singularity-induced nonadditive quantum communication in a qutrit platypus channel
Yu Guo, Bo-Xuan Wang, Xiao-Min Hu +4
The nonadditivity of channel capacity is a defining feature that distinguishes quantum communication from classical communication. In the quantum realm, the channel capacity is det…
Binarisation-loophole-free observation of high-dimensional quantum nonlocality
Jia-le Miao, Elna Svegborn, Zhuo Chen +7
Bell inequality tests based on high-dimensional entanglement usually require measurements that can resolve multiple possible outcomes. However, the implementation of high-dimension…
