Long-distance continuous-variable quantum key distribution over 100-km fiber with local local oscillator

Science Advances, 2023
Quantum key distribution (QKD) enables two remote parties to share encryption keys with security based on the laws of physics. Continuous-variable (CV) QKD with coherent states and coherent detection integrates well with existing telecommunication ...

Drone-Based Quantum Key Distribution

Conference on Lasers and Electro-Optics, 2023
Quantum networks between mobile platforms enable secure communication, distributed quantum sensors, and quantum computing networks. Here we present data from a quantum key distribution system between two aerial drones separated by 10 m.

The Evolution of Quantum Key Distribution Networks: On the Road to the Qinternet

IEEE Communications Surveys and Tutorials, 2022
Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol capable of maintaining information-theoretic security. Given the recent advances in QKD networks, they have evolved from academic research to some preliminary ...

Quantum key distribution

2021
Quantum key distribution (QKD) provides a means of secure communication between two parties. QKD exploits the principle that you cannot eavesdrop on a quantum communication channel without producing a detectable disturbance.

Overcoming the rate–distance limit of quantum key distribution without quantum repeaters

Nature, 2018
Quantum key distribution (QKD)1,2 allows two distant parties to share encryption keys with security based on physical laws. Experimentally, QKD has been implemented via optical means, achieving key rates of 1.26 megabits per second over 50 kilometres of ...

Quantum Key Distribution [PDF]

, 2010
In this chapter a complete QKD protocol is presented, starting from the transmission via the quantum channel up to the communication over the public channel. The protocol described here is the BB84 protocol, named after Bennett and Brassard [5]. There are other protocols like the B92 protocol [3], the six-state protocol [8], the SARG protocol [19] and ...

Floodlight Quantum Key Distribution

Conference on Lasers and Electro-Optics, 2016
Floodlight quantum key distribution (FL-QKD) is capable of Gbit/s secret-key rates over metropolitan area distances without multiplexing. This talk summarizes the FL-QKD protocol, its potential secret-key rates, and its proof-of-principle experimental demonstration.
