Secret sharing is a multiparty cryptographic primitive that can be applied to a network of partially distrustful parties for encrypting data that is both sensitive (it must remain secure) and… Weiter »Sharing Classical Secrets with Continuous-Variable Entanglement: Composable
Security and Network Coding Advantage
A global quantum repeater network involving satellite-based links is likely to have advantages over fiber-based networks in terms of long-distance communication, since the photon losses in free space scale only… Weiter »Simulating quantum repeater strategies for multiple satellites
The identification capacity region of the compound broadcast channel is determined under an average error criterion, where the sender has no channel state information. We give single-letter identification capacity formulas… Weiter »Identification over Compound Multiple-Input Multiple-Output Broadcast Channels
The derivation of ultimate limits to communication over certain quantum repeater networks have provided extremely valuable benchmarks for assessing near-term quantum communication protocols. However, these bounds are usually derived in… Weiter »Rate limits in quantum networks with lossy repeaters
Elementary building blocks for quantum repeaters based on fiber channels and memory stations are analyzed. Implementations are considered for three different physical platforms, for which suitable components are available: quantum… Weiter »Extending Quantum Links: Modules for Fiber- and Memory-Based Quantum Repeaters
