1002 km twin-field quantum key distribution with finite-key analysis

open access: yesQuantum 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.

A Design of Secure Communication Architecture Applying Quantum Cryptography

open access: yesJournal of Information Science Theory and Practice, 2022
Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short ...

The Case for Quantum Key Distribution [PDF]

open access: yes, 2009
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Weak Randomness

open access: yesEntropy, 2022
Sending-or-not sending twin-field quantum key distribution (SNS TF-QKD) has the advantage of tolerating large amounts of misalignment errors, and its key rate can exceed the linear bound of repeaterless quantum key distribution.

EVALUATION OF QUANTUM KEY DISTRIBUTION BY SIMULATION

open access: yesIraqi Journal of Information & Communication Technology, 2022
Quantum key distribution is a secure method for exchanging keys across communication entities. The first quantum key distribution (QKD) protocol, BB84, was introduced in 1984. The primary paradigm of QKD was initiated for a depolarizing channel.

Prefixed-Threshold Real-Time Selection for Free-Space Sending-or-Not Twin-Field Quantum Key Distribution

open access: yesEntropy, 2022
As a variant of the twin-field quantum key distribution (TF-QKD), the sending-or-not twin-field quantum key distribution (SNS TF-QKD) is famous for its higher tolerance of misalignment error, in addition to the capacity of surpassing the rate–distance ...

Toward Quantum Secured Distributed Energy Resources: Adoption of Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD) [PDF]

open access: yesEnergies, 2022
Quantum computing is a game-changing technology that affects modern cryptography and security systems including distributed energy resources (DERs) systems. Since the new quantum era is coming soon in 5–10 years, it is crucial to prepare and develop quantum-safe DER systems.
