Quantum network nonlocality sharing provides a unique perspective for constructing large-scale quantum networks and holds promise numerous potential applications. In this paper we demonstrate the via unsharp measurements in two-forked $n$-layer tree-shaped network, which features ${2}^{n}\ensuremath{-}2$ independent sources ${2}^{n}\ensuremath{-}1$ nodes. We investigate $({2}^{n}\ensuremath{-}2)$-local scenarios any $m$-sided sequential measurements, conclude that arbitrarily many observers...
<title>Abstract</title> Bell nonlocality is a valuable resource in quantum information processing tasks. Scientists are interested whether single entangled state can generate long sequence of nonlocal correlations. Previous work has accomplished sequential tripartite sharing through unsharp measurements. In this paper, we investigate the using only projective measurements and classical randomness. For generalized GHZ state, have demonstrated that unbiased measurement choices, two Charlies...
