Effect of a Temperature Gradient on the Screening Properties of Ionic Fluids
Andrea Grisafi, Federico Grasselli
The electrostatic screening properties of ionic fluids are of paramount importance in countless physical processes. Yet, the behavior of ionic conductors out of thermal equilibrium…
Satellite-Based Quantum Key Distribution in the Presence of Bypass Channels
Masoud Ghalaii, Sima Bahrani, Carlo Liorni +9
The security of prepare-and-measure satellite-based quantum key distribution (QKD), under restricted eavesdropping scenarios, is addressed. We particularly consider cases where the…
Overcoming fundamental bounds on quantum conference key agreement
Giacomo Carrara, Gláucia Murta, Federico Grasselli
Twin-Field Quantum Key Distribution (TF-QKD) enables two distant parties to establish a shared secret key, by interfering weak coherent pulses (WCPs) in an intermediate measuring s…
Boosting device-independent cryptography with tripartite nonlocality
Federico Grasselli, Gláucia Murta, Hermann Kampermann +1
Device-independent (DI) protocols, such as DI conference key agreement (DICKA) and DI randomness expansion (DIRE), certify private randomness by observing nonlocal correlations whe…
Conference key agreement in a quantum network
Alexander Pickston, Joseph Ho, Andrés Ulibarrena +6
Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be effi…
Topology, oxidation states, and charge transport in ionic conductors
Paolo Pegolo, Stefano Baroni, Federico Grasselli
Recent theoretical advances, based on a combination of concepts from Thouless' topological theory of adiabatic charge transport and a newly introduced gauge-invariance principle fo…
