High-rate multipartite quantum secret sharing with composable security
Russell M. J. Brooks, Joseph Ho, Joseph Niblo +5
Future quantum communication networks will conceivably support cryptographic tasks that require entanglement among more than two users. Quantum secret sharing is a prime example wh…
Strategy optimization for quantum conference key agreement in asymmetric star networks
Janka Memmen, Julia Kunzelmann, Nathan Walk +2
The distribution of entangled states is a core task for quantum networks facilitating quantum communication, and the use of multipartite entangled states comes with its own set of…
How to share Multipartite Entanglement in a Real-World Linear Network Connecting Two Metropoles
Janka Memmen, Anna Pappa
The development of large-scale quantum communication networks necessitates the efficient distribution of quantum states to enable advanced cryptographic applications and distribute…
Advantage of multi-partite entanglement for quantum cryptography over long and short ranged networks
Janka Memmen, Jens Eisert, Nathan Walk
The increasing sophistication of available quantum networks has seen a corresponding growth in the pursuit of multi-partite cryptographic protocols. Whilst the use of multi-partite…
