Significant progress has been made in satellite-based quantum key distribution (QKD), and
urgent follow-up work is to explore the optimal solution for building practical quantum …

A typical implementation of BB84 protocol for quantum communication uses four laser
diodes for transmitting weak coherent pulses, which may not have the same characteristics …

Vulnerabilities of components used in quantum-key-distribution systems affect its
implementation security and must be taken into consideration during system development …

The contemporary smart educational environment uses different information technologies
like social networks, virtual laboratories, augmented reality, artificial intelligence, big data …

We propose a modified version of the Bennett–Brassard 1984 quantum key distribution
protocol intended to tolerate losses, certain forms of noise, and the so-called photon-number …

Quantum key distribution (QKD) has rapidly developed recently. The repetition frequency of
the QKD system increases from tens or hundreds of MHz to GHz. A laser diode (LD) …

In this paper we present the approach for description of quantum control attack based on
combined protocol and hardware loopholes. It consolidates intercept-resend attack and …

Quantum key distribution (QKD) provides a methodology for secure key distribution based
on fundamental physical laws. Although significant experimental progress has been made …
