چکیده
The Bell inequality can provide a useful witness for device-independent applications with quantum (or postquantum) eavesdroppers. This feature holds only single entangled systems. Our goal is to explore model networks. We first propose verify the genuinely multipartite nonlocality of connected networks including cyclic and universal computational resources measurement-based computation model. further used construct monogamy relation in fully multisource resources. It finally applied multiparty key distribution, blind computation, secret sharing. present inspire various large-scale on manner.

Fully device-independent quantum key distribution.
Quantum cryptography promises levels of security that are impossible to replicate in a classical world. Can this security be guaranteed even when the quantum devices on which the protocol relies are untrusted? This central question dates back to the early 1990s when the challenge of achieving device-independent quantum key distribution was first formulated. We answer this challenge by rigorousl...
متن کاملTowards Device-Independent Information Processing on General Quantum Networks.
The violation of certain Bell inequalities allows for device-independent information processing secure against nonsignaling eavesdroppers. However, this only holds for the Bell network, in which two or more agents perform local measurements on a single shared source of entanglement. To overcome the practical constraints that entangled systems can only be transmitted over relatively short distan...
متن کاملDevice-independent quantum key distribution
Quantum key distribution allows two parties connected by a quantum channel to establish a secret key that is unknown to any unauthorized third party. The secrecy of this key is based on the laws of quantum physics. For security, however, it is crucial that the honest parties are able to control their physical devices accurately and completely. The goal of device-independent quantum key distribu...

The structure of each DAG encodes conditional independence relations [19] among the nodes. For instance, the no-signalling conditions in the Bell network, P (A|X,Y ) = P (A|X), and P (B|X,Y ) = P (B|Y ), can be seen to directly follow [1] from the structure of the DAG depicted in Fig. 1(a). Indeed, the specification of the DAG subsumes and generalises the standard nosignalling relations [2–4]. ...
