Continuous-variable quantum cryptography with untrusted relays
Stefano Pirandola,Carlo Ottaviani,Gaetana Spedalieri,Christian Weedbrook,Samuel L. Braunstein +4 more
TL;DR: The possibility of long-distance high-rate quantum key distribution in network topologies where direct links are missing between two end-users and intermediate relays cannot be trusted is shown.
Proceedings ArticleDOI
Reverse Coherent Information
TL;DR: A family of entanglement distribution protocols assisted by classical feedback communication that gives an operational interpretation to reverse coherent information is defined, i.e., the symmetric counterpart of the well‐known coherent information.
Proceedings ArticleDOI
Quantum cryptography with an ideal local relay
Gaetana Spedalieri,Carlo Ottaviani,Samuel L. Braunstein,Tobias Gehring,Christian S. Jacobsen,Ulrik L. Andersen,Stefano Pirandola +6 more
TL;DR: The ideal case where Alice's channel is lossless, i.e., the relay is locally in her lab and the Bell detection is perfomed with unit efficiency is studied, which corresponds to the limit of a trusted local relay, where the detection loss can be re-scaled.

Quantum cryptography with an ideal local relay
Gaetana Spedalieri,Carlo Ottaviani,Samuel L. Braunstein,Tobias Gehring,Christian S. Jacobsen,Ulrik L. Andersen,Stefano Pirandola +6 more
TL;DR: In this article, the authors consider the case where Alice's channel is lossless, i.e., the relay is locally situated in her lab and the Bell detection is performed with unit efficiency.

Symmetric collective attacks for the eavesdropping of symmetric quantum key distribution
TL;DR: This work considers the collective eavesdropping of the BB84 and six-state protocols and shows how these symmetric collective attacks are sufficiently strong in order to minimize the Devetak-Winter rates.
