Quantum correlation is a fundamental resource for various quantum information tasks. It thus of importance to share the utilize it many parties, but sharing among multiple parties strictly restricted by well-known monogamy relations. Nonetheless, this restriction can be relaxed when weak measurements are employed. Here, we experimentally demonstrate multiple-observer steering exploiting sequential measurements. Specifically, observe simultaneous triple violations inequality four observers...
We propose a quantum message authentication scheme that provides integrity and origin using remote state preparation. Authentication is one of the security services must be provided in secure communication. Quantum base for realizing known to technique even forthcoming computer environment. The proposed creates code (QMAC) with only single qubit measurement. It therefore easy implement operate compared existing technology normally generates QMAC Bell measurement or controlled unitary...
Abstract Quantum entanglement lies at the heart of quantum mechanics in both fundamental and practical aspects. The states has been studied widely theoretically experimentally, however, operators not much experimentally spite its importance. Here, we propose a scheme to realize arbitrary entangled operations based on coherent superposition local with non-zero probability failure. Then, implement several intriguing two-qubit photonic systems. We also discuss generalization our extend number...
