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

Entropy, 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.

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

Entropy, 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 ...

Comparison of Discrete Variable and Continuous Variable Quantum Key Distribution Protocols with Phase Noise in the Thermal-Loss Channel [PDF]

Quantum
Discrete-variable (DV) quantum key distribution (QKD) based on single-photon detectors and sources have been successfully deployed for long-range secure key distribution. On the other hand, continuous-variable (CV) quantum key distribution (QKD) based on

EVALUATION OF QUANTUM KEY DISTRIBUTION BY SIMULATION

Iraqi 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.
