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 (

Quantum Information Transmission Over a Partially Degradable Channel [PDF]
IEEE Access, 2014 We investigate a quantum coding for quantum communication over a partially degradable (PD) quantum channel. For a PD channel, the degraded environment state can be expressed from the channel output state up to a degrading map.

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 ...

Microwave Photonics Parallel Quantum Key Distribution
IEEE Photonics Journal, 2012 The incorporation of multiplexing techniques used in microwave photonics to quantum key distribution (QKD) systems brings important advantages by enabling the simultaneous and parallel delivery of multiple keys between a central station and different end-

Increasing the Link‐distance of Free‐space Quantum Coherent Communication with Large Area Detectors
IET Quantum Communication, 2021 A large area photo‐diode based homodyne detector for free‐space quantum coherent communication is reported. The detector's performance is studied in terms of the detection bandwidth and electronic noise for shot‐noise limited quantum signal detection ...

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.
