Quantum information processing (QIP) with solid state spin qubits strongly depends on the efficient Quantum information processing (QIP) with solid state spin qubits strongly depends on the efficient initialisation of… Weiter »Coherence of a charge stabilised tin-vacancy spin in diamond
Transmission of classical information over a quantum state-dependent channel is considered, when the encoder can measure channel side information (CSI) and is required to mask information on the quantum channel… Weiter »Classical State Masking over a Quantum Channel
Entanglement resources can increase transmission rates substantially. Unfortunately, entanglement is a fragile resource that is quickly degraded by decoherence effects. In order to generate entanglement for optical communication, the transmitter… Weiter »Communication with Unreliable Entanglement Assistance
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
