Revealing Tripartite Quantum Discord with Tripartite Information Diagram
A new measure based on the tripartite information diagram is proposed for identifying quantum discord in tripartite systems. The proposed measure generalizes the mutual information underlying discord from bipartite to tripartite systems, and utilizes both one-particle and two-particle projective measurements to reveal the characteristics of the tripartite quantum discord. The feasibility of the...
متن کاملRevealing Hidden Genuine Tripartite Nonlocality
Nonlocal correlations arising from measurements on tripartite entangled states can be classified into two groups, one genuinely 3−way nonlocal and other local with respect to some bipartition. Still, whether a genuinely tripartite entangled quantum state can exhibit genuine 3−way nonlocality, remains a challenging problem so far as measurement context is concerned. Here we introduce a novel app...
متن کاملTripartite Blind Quantum Computation
This paper proposes a model of tripartite blind quantum computation (TBQC), in which three independent participants hold different resources and accomplish a computational task through cooperation. The three participants are called C,S,T separately, where C needs to compute on his private data, and T has the required quantum algorithm, and S provides sufficient quantum computational resources. ...
متن کاملTripartite quantum state sharing.
We demonstrate a multipartite protocol to securely distribute and reconstruct a quantum state. A secret quantum state is encoded into a tripartite entangled state and distributed to three players. By collaborating, any two of the three players can reconstruct the state, while individual players obtain nothing. We characterize this (2,3) threshold quantum state sharing scheme in terms of fidelit...
متن کاملSeparability of Tripartite Quantum Systems
i pi = 1. Many separability criteria have been found in recent years. For pure states, the problem is completely solved, e.g., by using the Schmidt decomposition [1]. For mixed states, there are separability criteria such as PPT, reduction, majorization, realignment etc. [2, 3, 4, 5, 6]. In [7] the authors have given a lower bound of concurrence for tripartite quantum states which can be used t...
