Entanglement swapping and heralding are at the heart of many protocols for distributed quantum information. For photons, this typically involves Bell state measurements based on two-photon interference effects. In this… Weiter »Two-Photon Interference of Single Photons from Dissimilar Sources
Communication over a quantum multiple-access channel (MAC) with cribbing encoders is considered, whereby Transmitter 2 performs a measurement on a system that is entangled with Transmitter 1. Based on the… Weiter »The Quantum Multiple-Access Channel with Cribbing Encoders
We demonstrate experimentally the long-standing fundamental theoretical prediction that quantum two-level systems can only be efficiently resonantly excited via multi-photon pulses involving an odd number of photons. This prediction can… Weiter »Three-photon excitation of quantum two-level systems
Identification over quantum broadcast channels is considered. As opposed to the information transmission task, the decoder only identifies whether a message of his choosing was sent or not. This relaxation… Weiter »Identification Over Quantum Broadcast Channels
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
