Certification of Genuine Multipartite Entanglement with General and Robust Device-independent Witnesses
Chao Zhang, Wen-Hao Zhang, Pavel Sekatski +12
Genuine multipartite entanglement represents the strongest type of entanglement, which is an essential resource for quantum information processing. Standard methods to detect genui…
Device-independent detection of genuine multipartite entanglement for all pure states
M. Zwerger, W. Dür, J. -D. Bancal +1
We show that genuine multipartite entanglement of all multipartite pure states in arbitrary finite dimension can be detected in a device-independent way by employing bipartite Bell…
Multipartite state generation in quantum networks with optimal scaling
Julius Wallnöfer, Alexander Pirker, Michael Zwerger +1
We introduce a repeater scheme to efficiently distribute multipartite entangled states in a quantum network with optimal scaling. The scheme allows to generate graph states such as…
Simple proof of confidentiality for private quantum channels in noisy environments
A. Pirker, M. Zwerger, V. Dunjko +2
Complete security proofs for quantum communication protocols can be notoriously involved, which convolutes their verification, and obfuscates the key physical insights the security…
