Satellite Quantum Communications When Man-in-the-Middle Attacks Are Excluded [PDF]
Entropy, 2019 An application of quantum communications is the transmission of qubits to create shared symmetric encryption keys in a process called quantum key distribution (QKD). Contrary to public-private key encryption, symmetric encryption is considered safe from (

Fundamental limits of repeaterless quantum communications [PDF]
Nature Communications, 2017 Quantum communications will be used to transmit entanglement and secure keys, but it is important to estimate their optimal transfer rates. Here the authors compute the fundamental limit of repeaterless quantum communications for the most relevant ...

Environment-assisted bosonic quantum communications
npj Quantum Information, 2021 We consider a quantum relay that is used by two parties to perform several continuous-variable protocols of quantum communication, from entanglement distribution (swapping and distillation) to quantum teleportation, and quantum key distribution.
