Experimental demonstration of full network nonlocality in the bilocal scenario

Understand

Quantum correlation between nodes in a network which consist of several independent sources of entanglement and in multipartite entanglement systems are important for general understanding of the nature of nonlocality, quantum information processing and communication.

• In previous years, demonstrations of network nonlocality for bilocal scenarios have been in the focus.
• Yet, it has been found that the seminal protocols do not certify entanglement between end nodes, which otherwise require all sources in the network to be of nonlocal nature.
• This has motivated for development of even stronger concept, called full network nonlocality.
