We demonstrate the verification protocol in a three- and four-party setting using polarization-entangled photons, thus highlighting its potential for realistic quantum communication and networking applications. We will also&nbsp;discuss the challenges of constructing steering inequalities resistant to loss\/postselection, and look at how entanglement, steerability and state fidelity can be quantified in this setting.<\/em><\/div>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>We&#8217;ll discuss an entanglement verification protocol that allows any party in a network to check if a source is distributing a genuinely multipartite entangled state, even in the presence of distrustful parties and loss.&nbsp;The protocol remains secure against dishonest behavior of the source and other parties, including the use of system imperfections to their advantage.
