New constructions of multipartite entanglement resistant to particle loss
Wanchen Zhang, Zicheng Han, Fei Shi +1
An entangled state is called m-resistant if it remains entangled after losing an arbitrary subset of mparticles but becomes fully separable after losing any number of particles lar…

Extremal Maximal Entanglement
Wanchen Zhang, Yu Ning, Fei Shi +1
A pure multipartite quantum state is called absolutely maximally entangled if all reductions of no more than half of the parties are maximally mixed. However, an -qubit absolute…

Almost all even-particle pure states are determined by their half-body marginals
Wanchen Zhang, Fei Shi, Xiande Zhang
Determining whether the original global state is uniquely determined by its local marginals is a prerequisite for some efficient tools for characterizing quantum states. This paper…
