A Novel Scheme With Honest Relay for Secret Key Distribution

IEEE Access
Original quantum key distribution (QKD) protocols operate on a peer-to-peer basis between two adjacent nodes, which are directly connected through a quantum channel. Such protocols are severely distance limited.

Device-independent quantum key distribution with random key basis

Nature Communications, 2021
Device-independent quantum key distribution aims at the ultimate quantum-based unconditional security, but current protocols’ rates are quite far from anything practical.

Passive Decoy-State Quantum Key Distribution with Coherent Light

Entropy, 2015
Signal state preparation in quantum key distribution schemes can be realized using either an active or a passive source. Passive sources might be valuable in some scenarios; for instance, in those experimental setups operating at high transmission rates,

Quantum Key Distribution Over Double-Layer Quantum Satellite Networks

IEEE Access, 2020
Quantum key distribution (QKD) has attracted much attention on secure communications across global networks. QKD over satellite networks can overcome the limitations of terrestrial optical networks, such as large attenuation over long distance fiber ...

Quantum key distribution using unknown quantum states

AIP Advances
This paper proposes a version of quantum key distribution (QKD) by leveraging unknown quantum states. The measurement made on the unknown quantum states is independent of them.

Memory-assisted measurement-device-independent quantum key distribution

New Journal of Physics, 2014
A protocol with the potential of beating the existing distance records for conventional quantum key distribution (QKD) systems is proposed. It borrows ideas from quantum repeaters by using memories in the middle of the link, and that of measurement ...

Numerical finite-key analysis of quantum key distribution

npj Quantum Information, 2020
Quantum key distribution (QKD) allows for secure communications safe against attacks by quantum computers. QKD protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments,

Design and analysis of communication protocols for quantum repeater networks

New Journal of Physics, 2016
We analyze how the performance of a quantum-repeater network depends on the protocol employed to distribute entanglement, and we find that the choice of repeater-to-repeater link protocol has a profound impact on entanglement-distribution rate as a ...
