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…
