The ideal wavelength for daylight free-space quantum key distribution [PDF]
APL Quantum, 2023 Quantum key distribution (QKD) has matured in recent years from laboratory proof-of-principle demonstrations to commercially available systems. One of the major bottlenecks is the limited communication distance in fiber networks due to the exponential ...

Cost-Optimization-Based Quantum Key Distribution over Quantum Key Pool Optical Networks
Entropy, 2023 The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks ...

Simple proof of security of the BB84 quantum key distribution protocol [PDF]
Physical Review Letters, 2000 We prove that the 1984 protocol of Bennett and Brassard (BB84) for quantum key distribution is secure. We first give a key distribution protocol based on entanglement purification, which can be proven secure using methods from Lo and Chau's proof of ...

Quantum Key Distribution Using a Quantum Emitter in Hexagonal Boron Nitride [PDF]
Advanced Quantum Technologies, 2023 Quantum key distribution (QKD) is considered the most immediate application to be widely implemented among a variety of potential quantum technologies. QKD enables sharing secret keys between distant users by using photons as information carriers.

1002 km twin-field quantum key distribution with finite-key analysis [PDF]
Quantum Frontiers, 2023 Quantum key distribution (QKD) holds the potential to establish secure keys over long distances. The distance of point-to-point QKD secure key distribution is primarily impeded by the transmission loss inherent to the channel.
