Detecting -nonstretchability via a class of informationally complete symmetric measurements
Yan Hong, Mengjia Zhang, Limin Gao +2
Characterizing multipartite entanglement is a fundamental problem in quantum information theory. The concept of -stretchability provides a framework for characterizing the struc…
